Update on my previous post regarding screen garbage when switching back
into text mode (I use GrSetMode(GR_default_text), which works fine under
DOS but leaves an unusable garbage/blinking colored screen under Windows
3.1 & 95):

Thanks for the suggestion to save & restore text info, either with program
or through PIF file. However the problem is not simply that the screen is
garbaged, but that some pointer has been shifted so that any subsequent
typed text does not appear on the screen. Oddly enought the little
blinking underline cursor DOES appear, but nothing I type; the colored
blinking letters are fixed. Looks the the displayed text screen has been
shifted to some unused portion of display memory, while the text is being
written to another portion of memory. 

How do I reset the display memory pointer? This must be written down
somewhere; can anyone give me a reference? Thanks!
