: timer event as well. Problem is that my screens don't seem to update
: when using GrGetNextEventTimeout. Everything else looks right in the
: code. I'm basically using a couple of offscreen windows, and when one
: taps/clicks on a tab-like-thingy to change the 'mode', I switch the
: exposed window with GrCopyArea.
I assume that everything except for the clock works perfectly
when not using the GetNextEventTimeout. If not, my response
won't apply.
There is a small possibility that your application is falling prey to
the bug that we just fixed in 0.89pre7 (to be released hopefully tonight).
In this case, if you return from a GetNextTimeout w/o timeing out,
and then you execute another GrXXX call, you may lose events,
and it sounds like you're losing the expose event. Try commenting
out any draw/server calls during timeout processing. If that fixes
the problem, then my client.c fix should fix this problem as well.

Greg
