Most likely, it's the mouse handler. When you quit the program, the memory
used by the handler previously gets freed. The system works fine for
sometime or until you do something that uses memory (ex: running another
program).

The solution is to just reset the mouse just before exiting the program
(you could put that in an atexit function).
