The problem is that the changes take effect after gtk has reentered its event-loop. Which won't happen until your programs terminate. If your goal is only to display the messages, there is certainly a way to process the event loop for one iteration. Try and google for GTK event loops. If you want to display an continuous update, you will have to install a timer event, and start the burning as subprocesses. Regards, Diez -- http://mail.python.org/mailman/listinfo/python-list
