The way I would do this is to have the class containing the button handler save a reference to the window. When the window is closed then set the reference to None. Then the button handler can check to see if it already has a window. Alternately you could just create a single, hidden window at startup, then the button shows the window and the close box just hides it instead of destroying it. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
