Hi Alan, Yes, Tkinter queries up a bunch of events to refresh the window, but doesn't execute them directly until it has a chance to take control, that is, when control passes back into the mainloop. You can manually force a refresh of the window-refreshing events through the loop. Use update_idletasks() methods on the toplevel Tk, and it should refresh things properly. See: http://www.pythonware.com/library/tkinter/introduction/x9374-event-processing.htm which talks about it a little more. Hope this helps! _______________________________________________ Tutor maillist - [email protected] http://mail.python.org/mailman/listinfo/tutor
