Does the API call to stop get called? On Linux, the performance is stopped, the main problem there is that the messages are not printed (I already know why this happens, though). However, I often get crashes at least on Windows. I will probably change the code so that the stop button only sets a flag, rather than trying to actually stop the performance from the FLTK callback.
