We solved the problem by increasing the system heap space.
Normally the system has a small amount of heap space available. We increased
the space using CE Software's Heapfixer, and all the problems went away.
We also checked with both Solutions International and Microsoft, and neither
was aware of any other conflicts.
Microsoft, however, strongly recommends that anyone using 24-bit graphics in
PowerPoint upgrade to version 2.0.1d.
