Thanks, but I was just explaining why I don't want to call mainloop(). In my original example, I can type Application() at the interactive prompt and get a GUI (which seems to work apart from not quitting properly and leaving a messed-up terminal on some versions of linux) while still being able to use the interactive interpreter. I need to find out what cleanup is performed after mainloop() exists, I guess. Incidentally, I found the information in the thread http://thread.gmane.org/gmane.comp.python.scientific.user/4153 quite useful regarding mainloop() and being able to use python interactively from the prompt while still having a GUI. -- http://mail.python.org/mailman/listinfo/python-list
