You are right however this case is a bit different. The application is a keylogger which listens for keyboard events. The GUI is done using Wx. They are different message loops. Under Linux I have no problem however in the case of Windows I don't know how to stop the keylogger. The Keylogger for Windows is very simple, see: http://retypingdante.svn.sourceforge.net/viewvc/retypingdante/trunk/inferno/src/rtd_Wkeylog.py?view=markup As you can see in the cancel function I cannot use win32gui.PostQuitMessage(1) since it kills the whole app, including Wx, and not just the thread. I cannot mix the eventloops of Windows and Wx AFAIK so I put it in its own thread. I'm already using Queue objects to pass the data between threads.
