I've been doing this for a while.  You have to update the windows with
InvalRect and the desktop and assorted other areas with CALL PAINTBEHIND
and CALL DRAWMENUBAR.  

Just out of curiousity, are you able to draw to video memory in 16 bit
mode?  I can't seem to puzzle that out, but 8 works fine for me anyway.

I have a code snippet to update the whole desktop and menubar, but windows
must be done normally.
