The other day, I installed 5.1 on my home Power Center Pro running OS
8.1, and a funny thing happened (at least, something that didn't happen
under 5.0.3): a routine
that calls LOADCT and then CW_ANIMATE produced only grey-scale movies
until I set the graphics... option under the Edit -> Preferences menu item
to "Pseudo (8-bit)."
I can still get any 256 colors I want, but why this change?
