I seem to having a little problem. I just got a fractal program from simtel
that does fractals in some super VGA modes. I want to be able to generate
fractals in the background while doing something else, but I can't switch back
to the program manager without getting a bunch of garbage on the screen. The
Windows reference states that if you set the video memory for 'High Graphics'
in the PIF file, it sets aside 128K for the video memory. The mode I am 
mainly interested in, 640x480x256, obviously needs more than 128K. However,
it runs fine in the foreground. Yes, I clicked on retain video memory, but
still the same problem... the same for Monitor port set for High Graphics. 
Is there any way that I can set aside extra memory for the video? Or isn't
this the problem? Has anyone else had this problem in super VGA modes? Any 
help will be greatly appreciated. Thanks.

By the way, if it matters, the configuration is:
   -386/25Mhz, AMI Bios (4/30/89), MS-DOS 4.01, ATI VGA Wonder w/ 512K
