I see, this happens only with cascade menus, in my example I only had a
popup menu, for which it worked as expected. Right now I am trying to
figure out what's wrong with Tkinter (it's definitely a bug within
Tkinter.py, and I doubt that it has been fixed since 2.6.5), I'll send
another post when I know more. Of course for now you are right, your code
"just works" :)

Regards

Michael
