You need to give some time to the GUI so it can draw. A minimal solution is to call root.update_idletasks() after you set the button to green. If you want the GUI to be responsive you have to run the socket in a separate thread; this recipe may give you some help though it may be more complex than you need: http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/82965 Kent -- http://mail.python.org/mailman/listinfo/python-list
