Acrobat Reader v. 4.0 - Known Issues
-------------------------------------------

General Information
-------------------

1.  Blank Pages in Web Browsers - Some pages of PDF files may appear blank
    when viewed within Web browsers.  This may occur if the PDF file is
    being served from an early versions of some Web servers (such as the
    Microsoft Internet Information Server version 2.0).  Users can view
    such PDF files by saving a copy locally.  Webmasters may need to
    update their server to the latest version (for more information see
    http://www.adobe.com/prodindex/acrobat/byteserve.html).

2.  Launching external applications / Security - PDF files may contain
    instructions to launch an external application or to open a non-PDF
    file.  To enhance the security of PDF files , in Acrobat Reader version 4.0
    will prompt users with an alert before launching
    an external application, an executable file or a command.

    The alert will say: "Acrobat is about to launch this application: "
    [Application] "Allow this action (yes) or all actions to all
    applications (all)?"  followed by three buttons, "Yes", "No", and "All".
    - Choosing "Yes" will allow only this instance of this action.  
    - Choosing "No" will prevent this instance of this action.
    - Choosing "All" will allow all instances of all actions, thus
    disabling the alert until Acrobat is exited and restarted.

Information for Acrobat Reader v. 4.0 
-------------------------------------

Known Issues for Acrobat Reader Working with Netscape
-----------------------------------------------------

If you encounter problems where PDF documents do not render in Netscape,
Netscape hangs, or document transmission stalls, you may disable PDF rendering
in the Netscape window and use the viewer as a "Helper Application".

To disable PDF rendering in the Netscape window:

1. Pull down the "Options" menu item and select "General Preferences".  On the
   "General Options" dialog, select the "Helpers" tab item.  Find the item in
   the list of helper applications that looks like the following: 

      application/pdf      Plug In : nppdf.so

2. Select this item. 

3. Select the "Edit ..." button to modify this entry. In the dialog box, select
   the item marked "Application" and enter the pathname to the Acrobat Reader 
   product along with the "%s" field identifier for the temporary file name. 
   For example, if Acrobat Reader is installed in /usr/local/Acrobat3 then
   enter the following in the text box for the application:

      /usr/local/Acrobat3/bin/acroread %s

4. Select the "OK" button in the "Netscape Helper" dialog box. 

5. Select the "OK" button in the "Netscape: General Preferences" dialog box. 
   The view in Netscape window feature has been disabled and Acrobat will act
   as a Netscape helper application.


Known Issues with Acrobat Reader 4.0
------------------------------------

General Information
-------------------
1.  Using NCD PC-Xware:
    A pink tint will appear when Smooth Fonts is turned on in General
    Preferences and the default visual is TrueColor 5-6-5 (RGB) in 16-bit mode
    (this is a PC-Xware problem).  This affects only the display, not the print
    result.
    SOLUTION: Change to a different visual (8-bit or 24-bit) or turn off the
    Smooth Fonts option.

2.  Acrobat Reader will not run correctly from a directory where the "pwd"
    command fails.
   
3.  We recommend you remove the file $HOME/.acrorc before running Acrobat 4.0
    for the first time.  This ensures the default preference settings are used
    when you first run Acrobat 4.0. This is not, however, a necessity, and may
    actually be undesirable if you wish to continue running Acrobat Exchange 3.0.
  
4.  Files listed in the File menu are "recent files" and depend upon exact path
    names. If you open a file in a session using and automounter and the
    automounter goes down, attempting to open the "recent file" will give a
    "No such file or directory" error.  This also occurs when the file is moved,
    renamed, or Reader is run from a different machine that does not have the
    same file systems mounted.

5.  To prevent temporary files opened when viewing PDF on the Web from
    appearing in the "recent files" list, set your mailcap entry as follows:
   
    application/pdf;acroread -tempFile %s

6.  Acrobat Reader does not warn the user when the preferences file cannot be
    written. Please make sure '$HOME/.acrorc' is writable if you wish to save
    preferences.

7.  Some Window managers may work better than others. Specifically, we have
    tested CDE, KDE, and Openwindows.
  
8.  Users cannot print password-protected PDF documents to PostScript from the
    command line even though they are able to print the files from Acrobat
    Reader.
  
9.  When operating in a heterogenous network enviroment using Novell servers, we
    recommend you avoid giving PDF files long names (greater than 32
    characters). A Novell server displays the long file name to a Macintosh
    user, but the Macintosh Operating System prevents Acrobat from opening the
    file. This is not a problem on Windows.
  
10. Modal dialog boxes may appear to be "buried" behind the main document
    window.  When they are behind the main window, they are still active and
    prevent the user from doing anything. To bring the dialog to the front,
    click anywhere in the main window. You can now dismiss the dialog and
    proceed.
   
11. At the command line, type 'acroread -help' or 'acroread -helpall' for more
    information on command line options. Note that when using these command
    lines you must still supply a DISPLAY variable if one is not already defined 
    in your environment. 

12. On a Tektronics X-Terminal:
    If displaying a document in Full Screen mode using a black background, a
    small white line will appear along the bottom and right edges of the
    background. This is due to a problem in the olwm running locally on the
    X-Terminal and is not an Acrobat bug.
  
13. Characters in PDF files that are not part of the ISO8859 encodings will not
    display when the text is selected and pasted elsewhere. This is most notable
    with the Registered and Trademark symbols. Printing is not affected and will
    work fine.
   
14. Printing: no document printed and/or error in lp log.
    When you lp foo.ps, it creates a symbolic link from the spool file to the
    foo.ps file.  This saves space on the file system.  Unfortunately, Acrobat
    creates a temporary file to spool, writes the PostScript out, and then
    deletes the temporary file before the lpd process can get hold of it.
    SOLUTION: Include the "-c" option (copy) on the lp command line.  This
    forces the lp process to copy the file to the spool area instead of making
    a link.

15. In Acrobat 3.0 and later it is possible to give a PDF file attributes for how it 
    should open (with or without Tool bar, etc.)  To make Acrobat ignore the 
    "Open" settings, keep the CTRL and Shift keys pressed down when 
    clicking OK in the File > Open dialog box.  For example, when opening a file
    which has been set to hide the Tool bar, it is not possible to then show the
    Tool bar for the file once it is open. If you need the Tool bar displayed, 
    you should close the file and re-open it making Acrobat ignore the "Open" 
    settings. 


Solaris-specific Information
----------------------------

1.  Text colors may change depending on zoom factor. This occurs when working in
    Solaris on a Sparcstation with a CG14 frame buffer and is a known problem
    with the CG14 frame buffer. Please contact Sun Microsystems for a patch.
    The following patches are available and should correct the problem:
  
      Solaris Release      Patch id
      ---------------      ---------
           2.5.1           103794-01
           2.5             103074-02
           2.4             101922-15
           2.3             101594-18

2.  A segmentation fault will occur when launching Acrobat Reader if your
    PSRESOURCEPATH includes /usr/openwin/lib/X11. This directory does not
    contain Type1 PostScript fonts and should not be included in the path
    statement.

3.  There is no search functionality available for the x86 Solaris version
    of the Acrobat reader.


HP-UX-specific Information
--------------------------
  
1.  You might receive warning messages indicating missing fonts. There are
    several messages you could receive depending on your configuration.

    - You are displaying on an X server that has no HP-ROMAN8 font defined. The
    message you receive is:
  
      Warning: No fonts available with charset "HP-ROMAN8", using "ISO8859-1"
   
    In this situation, upper-ascii characters will display incorrectly. To fix
    this, change your language to an ISO8859 language
    (e.g., setenv LANG american.iso88591).
  
    - The variable fontList is specified and its encoding doesn't match the
    encoding of the application. If you specified an ISO font list, you
    will receive an error that says the encoding for fontList doesn't match
    the locales encoding. You need to change your LANG variable as listed above.
   
    - The Helvetica used by the Motif toolkit is not available on the system in
    the hp-roman8 encoding. The message you might receive is:
  
    Warning: Cannot convert string
   "-adobe-helvetica-bold-r-normal-*-*-120-*-*-*-*-hp-roman8" to type FontStruct
  
    This occurs when you are running on HP but displaying on a non-HP system. To
    fix this, set an application resource for fontList to specify a font that
    exists on the system.

2.  The HP Motif library uses different virtual key bindings than Sun's. As a
    result, when running on a Sun and displaying on an HP, the keys for
    DeleteLine, DeleteChar, InsertLine, and InsertChar may not be properly
    defined by default. You can tell if you get warnings of the form
     'Warning: cannot convert string "<Key>DeleteChar" to type VirtualBinding'.
    One consequence of this is that the Esc key on some HP keyboards will not
    work to exit Full Screen mode.

    To fix this, load a file with the appropriate key bindings using the
    "xmbind" command.  See the man page for xmbind for where it looks for the
    file. Check the bindings using  "xprop -root | grep BIND".

    The resulting string should include hpDeleteLine, hpDeleteChar,
    hpInsertLine, and hpInsertChar.
    
3.  Support for viewing files with embedded ICC profiles, a new feature
    of Acrobat 4.0, is not support on the HP platform due to compiler issues.
    Currently, if you try to print a file with an embedded ICC profile, your
    viewer may crash.
   

AIX-specific Information
------------------------

AIX does not currently have the Netscape integration available. However, since
IBM has provided a solution for plugins in later versions of Navigator, we
plan to support this in our next reader.


IRIX-specific Information
-------------------------

None at this time.


OSF-specific Information
------------------------

None at this time.


Linux-specific Information
--------------------------

1.    There is currently no search functionality available for the Linux Acrobat
      Reader. 
      
2.    The current reader is "libc" based as opposed to glibc. This means that
      the Acrobat reader has been linked with libc.so.5 as opposed to libc.so.6.
      The repercussions of this are mainly that if you are using a "glibc" based
      version of netscape, you will not be able to launch the Reader as a plugin.
      Currently, the rpm version of Netscape is glibc based.
         Since things are moving in the glibc direction, we will be providing a
      glibc linked version of the reader in the 4.01 version.
