the "Instance and Class Bindings" section on this page:

http://www.pythonware.com/library/tkinter/introduction/events-and-bindings.htm

discusses a similar case.

the easiest solution is to return the string "break" from the
event handler.  (this prevents Tkinter from propagating the
event back to the standard handler).
