Troubleshooting Logitech Serial Mouse Problems in Windows 3.0 (64471)

WORKAROUND

You should remark out the LOGIMENU and CLICK TSR programs if they are listing in your AUTOEXEC.BAT file. In addition, if you find the GOMOUSE.BAT file, replace it with a MOUSE.COM file dated 10/02/89 because the GOMOUSE.BAT file may also contain LOGIMENU and CLICK.

If your mouse continues to exhibit problems, refer to the following troubleshooting sections to resolve the problem(s).

Mouse Pointer Doesn't Move or Doesn't Appear

In addition to problems caused by TSRs, you may notice that the Mouse pointer intermittently shows up in Windows 3.0 but does not move, or that the mouse pointer may not display at all.

1. Verify the Windows Logitech Serial Mouse Driver is installed by selecting the Setup icon from the Main group of Program Manager. Verify that the mouse driver file is the corect size and date: the Windows 3.0 file should be dated 5/1/90 and the 3.00a file should be dated 10/31/90; either version should be 3584 bytes in size. Files of different sizes or dates may still be compressed, or may be corrupted, or may have been provided with an OEM version of Windows. Also verify that a Microsoft VGA or EGA driver is loaded rather than a Super VGA driver.
2. If you have one of the following combinations, use TYPE=2 at the end of the WIN.INI file:

   BUS card and Logitech serial-type mouse (including serial Trackman)
   
   PS/2-type port and Logitech serial-type mouse (including serial Trackman)

   Copy the following example to the end of the WIN.INI file:

         [MOUSE]
         TYPE=2
   						

   NOTE: According to Logitech, TYPE=3 is no longer supported by the Windows 3.00 Logitech Serial Mouse driver.
3. Boot with a minimal CONFIG.SYS and AUTOEXEC.BAT.
   
   The CONFIG.SYS file should contain FILES=30, BUFFERS=30, DEVICE=HIMEM.SYS, and required disk-partitioning drivers.
   
   The AUTOEXEC.BAT file should contain PROMPT $P$G and a PATH command to DOS, WINDOWS, and the root directory.
   
   Reboot the machine with this configuration. When the machine reboots, the BIOS and DOS versions may be displayed along with the amount of memory. Write these down and verify that the DOS version is the correct version for the machine, and verify that the BIOS is at least 1988 or later.
4. Check that no other device is using the same interrupt. If the mouse is on COM1, then no other device should be set for Interrupt 4. If the mouse is on COM2, then no other device should be set for Interrupt 3.
5. Check the serial card containing COM ports for the Logitech Mouse. Look at the card for a square chip. It may read WINBOND with a number underneath it resembling W86C452P. If that chip exists, it should be replaced with a different serial-card model. (If replacing the card is not an option, proceed to Step 6).
6. If all else fails, re-install the Windows mouse driver for the following:

   Mouse Systems (or VisiOn) connected to COM1

   -OR-

   Mouse Systems (or VisiOn) connected to COM2

Problems After Starting MS-DOS Applications

Another problem you may have with the Logitech Mouse may occur when starting any MS-DOS application under Windows (including the MS-DOS prompt). In this case, quitting or switching back to Windows may cause erratic mouse movement. If the mouse pointer moves slowly, jumps from point to point on the screen, or moves at different speeds when running non-Windows applications, you may have a problem with the MS-DOS mouse-driver file. You can avoid this problem as follows:

1. Install version 4.10 of the Logitech Mouse Driver for MS-DOS systems that is usually located on the second disk of the Logitech MouseWare Utilities Disk for version 4.01.
   
   Do not confuse the version of the MouseWare Utilities Disk for 4.01 with the Logitech Mouse DOS Driver for version 4.10.
2. If Step 6 above was used to resolve Symptom #1, then you may have to create a batch file that contains the following two lines:

         <appname>.EXE {the name of the DOS application being run}
         MOUSE PC
   						

Follow the steps on Page 448 of the "Microsoft Windows User's Guide" that explain "Creating PIFs for Batch Files."
