The usual approach to this situation is to invoke the user code via a callback from the UI main loop or invoke it explicitely after the UI system has been set up immediately before its main loop is called. Might look somehow like this: main thread: from thread import start_new_thread from visual import setup_gui, start_main_loop setup_gui() # sets up the GUI subsystem start_new_thread(lambda: __import__(<your module>), ()) start_main_loop() -- http://mail.python.org/mailman/listinfo/python-list
