This code works "as is" on Windows XP. However, I have gotten this error when trying to run it from IDLE and I've heard that that can happen in other Tkinter-based IDEs. Try running it from the command line and I'll bet you won't get that error. Also, there's a great wxPython user's group you can join from the official website: www.wxpython.org Mike -- http://mail.python.org/mailman/listinfo/python-list
