On further investigation, I can't see any extra grabs occurring. But
upon looking at the changes in events.c (HandleEnterNotify and
HandleLeaveNotify), I see you've been wrestling with this general
problem already, a few months ago. It looks as though we may have some
more fine-tuning to do in that area.
I'm attaching the revised version of the test program - it's really
little more than a textbook example that *should* work as is.
Cheers,
Bob
