This doesn't have anything to do with focus loops or otherwise, it's because the OP isn't familiar with event based programming. You're performing a long-running task which is preventing the event loop from processing, so your text isn't updating and your application is unresponsive. You need to rewrite your task - either do everything asynchronously, or use a threaded approach. If you use the thread approach, be sure to not call the updates directly, you can use the wx.CallAfter mechanism to call gui functions in a threadsafe manner. There is a lot of information about this on the wxPython wiki and in the archives of the wxpython-users ML. -- http://mail.python.org/mailman/listinfo/python-list
