Normally only the main thread should alter the graphics - you'll have crashes if you try to do it otherwise. If you want to perform calculations in a separate thread to keep the GUI responsive, you have to send an event from the working thread to the main thread, so that the main thread does the GUI update. http://docs.wxwidgets.org/stable/wx_wxthreadoverview.html#wxthreadoverview Well, at least that's the story from my C++ wx knowledge, but it is probably still valid in Python. Another interesting read from the samples page: http://docs.wxwidgets.org/trunk/page_samples.html#page_samples_thread Maybe simply using wxMutexGUIEnter() / wxMutexGUILeave() will sort your problems, but I've not tried this method.
