BUG: RUN Command Hangs Form with WindowType=1 and Desktop=.T. (190545)

MORE INFORMATION

Steps to Reproduce Behavior

1. Run the following code from a program (.prg) file. In order to demonstrate the behavior, you need to run it in such a way that the Command window is the only window open when the program is started. You can do this by issuing the code DO <Filename.prg> in the Command window, where the filename is the name of the program file into which you have saved the code below. The program depends on the existence of a file called Autoexec.bat in your "C:\" directory. You can create a dummy file there if this file does not exist, or you could have the program copy a different file if you wish.

         DEFINE CLASS form1 AS FORM
            TOP = 0
            LEFT = 0
            HEIGHT = 206
            WIDTH = 231
            DESKTOP = .T.
            CAPTION = "Form1"
            WINDOWTYPE = 1
            NAME = "Form1"
   
            ADD OBJECT command1 AS COMMANDBUTTON WITH ;
               TOP = 120, ;
               LEFT = 72, ;
               HEIGHT = 27, ;
               WIDTH = 84, ;
               CAPTION = "Run XCopy", ;
               NAME = "Command1"
   
            PROCEDURE command1.CLICK
               RUN /N xcopy c:\autoexec.bat c:\autoexec.bak
            ENDPROC
   
         ENDDEFINE
   						

2. Click the "Run XCopy" button.

The MS-DOS box appears and disappears, and the form becomes deselected. The form cannot get the focus and will not receive keyboard or mouse input. If you click on the close box in the Visual FoxPro desktop, you will receive a "Cannot quit FoxPro" message. Once this has occurred, the form will be accessible once again. This does not happen with Desktop = .F. or with WindowType = 0 and a READ EVENTS.
