I came across the same problem while arguing with Wilf about colour in
PP 4.0 on a Mac IIci with the same graphics card.  The solution is to go
to the control panel and select the monitor resolution you want (even if
it is already selected) before running PP4. 

Back to the original problem: has anyone been able to get 24 bit images
to work? I forget the exact class name but we were unsuccessful in
getting something that was 24 bits deep.  Even trying to get something
from the clipboard didn't work (sure, you could display the image using
the Mac graphics handle but you couldn't get the actual bits into
a Smalltalk object).
