not really.  you seem to be doing something weird here...

event handler?  you shouldn't be using event handlers to
catch button clicks.  using the "command" option instead
should fix this.

or in other words, it sounds as if you're doing:

    b = Button(root, text="foo") # Button = button widget
    b.bind("<Button-1>", callback) # Button = mouse button

instead of:

    b = Button(root, text="foo", command=callback)

(note that the command callback takes no arguments,
while an event handler takes an event descriptor as its
only argument)
