I've also had some problems maintaining correct colours. I'm only
running 256 colours. Occasionaly however, the colours of even ordinary
(non-bitmap) graphics go wrong. MetaCard seems to like the desktop
pattern - its blue, so when MetaCard dosen't get colours correct, blue
appears everwhere! Indeed the splash screen has taken on a permenant
blue colour after changing the desktop pattern (though occasionaly, it
starts up as red or another horrible shade). Is the splash screen meant
to change colour?

Try setting the "alwaysbuffer" to true, e.g.:
set the alwaysbuffer of this stack to true
This fixed all my refresh problems. I was told that this was
intended mainly for slow machines, and whilst Pentium 90 isn't slow if
you are using lots of graphics it might just classify as such. (Somebody
please correct me if I'm wrong).
Hope this helps,
