Have you tried software rendering? This is the solution
I think I am going to adopt because I see I switched from
using EXPOSE events originally because of undocumented
changes in XManager that caused EXPOSE events to not be
handled correctly in blocking widgets. Sigh...

Now I am setting the RENDERER keyword to 0 on my
draw widget. That also seems to fix the problem for
me. I've left all the possible solution code in the
program so the user can choose his own poison.

I'll say this, that Python book is creeping closer and
closer to the place where I do all my work.

Cheers,

David
