   The program itself does very little during idle time. It just

   What are we doing about this? Well, in MacDraw Pro we have switched
   over to new system calls that better support MultiFinder (MacDraw
   II is a fairly old program as far as code goes). We've done a lot
   to optimize performance and help manage memory better.  For
   instance, MacDraw II keeps an offscreen buffer the same size and
   bit depth as the monitor.  We now crop the buffer as the window
   size shrinks and we don't let it grow too big.

These sound like great improvements, and I'm looking forward to
MacDraw Pro.  But there have been several times when MacDraw II 1.1 on
a IIci running 6.0.7 (no INITs; running either Finder or Multifinder)
just seems to take forever to respond to user events of any kind.
Clicking causes the pointer to change to the hand cursor -- which then
stays that way for a second or two before changing back into the
pointer.  It's fabulously annoying when it happens....

Anyway, we'll be getting Pro when it's released, and I suspect that
will be the end of our problems.  Thanks for the info.
