I've got some beta testers running a door of mine, some under
 DOS with Desqview, others under OS/2 Warp.  This door program can
 be configured so that the screen on the local BBS side will display
 in EGA mode (screen 9) or with ANSI codes in screen 0 sent through
 the standard output by doing an OPEN "CONS:" statement.  Both are
 having troubles with the EGA mode.
    OS/2:  The sysop says that when configured for EGA mode, it runs
 fine if the window is in the foreground, but freezes if put in the
 background, and unfreezes when brought again to the foreground.
 When run in ANSI mode, it works fine in both fore- and background
 windows.
    Desqview:  This sysop just has random lockups when in EGA mode,
 but no lockups in ANSI mode.
    The door runs perfectly on my straight DOS system.  It has never
 locked up for me in either mode.  The EGA code only does LINEs with
 and without filled or unfilled boxes, a bunch of PUTs and a lot of
 CLRPRINTs (from the \PB3\TIPS directory, the routine that lets you
 print text with a different background color than the current EGA
 background color).  It uses the time-slice sharing interrupts
 appropriate to its environment while waiting for input.
    Does anyone have any suggestions that I can either (a) use in my
 door to make it work under these conditions, or (b) pass along to
 these guys to configure their systems to handle PB-compiled
 programs running under these environments?  I don't have either
 OS/2 nor Desqview, so I can't test 'em at home and aren't familiar
 enough with 'em to come up with any suggestions on my own.
