  I dunno about "most" programs.   I don't know *any* commercial graphics
  programs which are well-behaved in the sense that they don't make 
  direct writes to the VGA control registers instead of only going
  through the BIOS calls, except for a few which are written explicitly
  for a multi-tasking environment, like CorelDraw for Windows.  Certainly
  popular programs like PC Paintbrush IV Plus are downright naughty.  
  When I asked ZSoft about this they said that they *had* to do it to
  get decent performance.

  Me, too.  A few hours ago I broke down (some say I've been broken
  down for a long time!) and ordered Windows 3.0 from PC Connection
  for $89 plus next-day shipping.  So I should have it tomorrow and
  I hope to give my initial impressions sometime next week.

  I did, I did!   In February I described the problems I was having and
  several people gave me various suggestions.  None of them worked but 
  did I write back and insult the net like another recent Desqview poster?!!
  No!!!    I know that on Usenet you get what you pay for.   (Now, if that
  were only true for certain software....)
