has nothing to do with scopes -- objects and assignments don't work
as you and your code expects.
short answer: first read:
http://effbot.org/guides/python-objects.htm
and then think about what the "setting=CurrentCanvasSetting" and
"setting=button.cget()" lines really do.
I'll leave it to alex to write the long, pedagogical explanation.
