Windoze seems to only understand some standard screen modes (and
possibly a few 'unusual' ones), choose one it does not know how to
handle and it fails to restore the window. I believe its a problem in
the screen grabber (possibly aided by your SGVA driver). I cannot safely
use 132*60 textmode because of this little oversight.
Windoze is a bottomless pit of bugs and unimplemented features...
