Hello,

I am currently using QuickC 2.5 to develop a simple computational fluid 
dynamics program.  I am running from a full screen Dos session, and all the
graphics calls I use seem to work just fine.  However, I decided ÿtn a
test case in the background and OS/2 said it could not support the graphics
mode in a window.  This is somewhat puzzling since the graphics mode is 
640x480x16 (_VRES16COLOR, for those of you who have used the MS routines),
and the desktop is running 800x600x256.

Is this a problem with the CSD TSENG drivers, MS QC, or simply some setting
that I need to change?

Current setup is:
	GA+SP TSENG 800x600x256 driver
	Diamond Speedstar HiColor (TSENG 4000 + HiColor RAMDAC)

Thanks in advance for any comments,

BTW:  What is the difficulty level increase in going to OS/2 non-PM programming
	with graphics (and PM for that matter)?
