Hi!
Thanks for the trace output.
As far as I can tell, I don't see a better location to place the test. (I
have to include myself in the group who have no idea why drawRect is being
called when the frame is miniatured.) I would suggest that we add it as you
originally suggested.
Alan, what do you say? Have you looked into this?
