This likely means that there is some thread in the application which is still active. Try enumerating all threads in the system with threading.enumerate() after quitting your main-loop, and printing to std-out or a logfile the names of all threads and some properties of them (such as daemon-thread yes/no).

If you're out of luck the thread is not created with the threading module however, but with the ancient thread module or some C library. In that case I don't know how to list all active threads of the application; you'd have to use Win32 specific calls. Perhaps you can attach some sort of debugger?

What might also help is to call sys.exit() after the main-loop has finished.
