In this case the method must return False, because it's a wxPython method that needs a True or False value. If it doesn't, the program will continue even after the error message. What I did to make it compact was have the error_message() method return False, so I can just call return self.error_message() -- http://mail.python.org/mailman/listinfo/python-list
