Ok this is a little weird for me. I’m usually the guy who fixes the bugs,
not the one who reports them 
There is this problem in the current ISp code that locks up the mouse on
certain systems when SDL_InitJoystick is called. I myself can’t reproduce
it, but if a certain person knows the limitations and assumptions the ISp
code makes about the system you’re running on, that would be helpful. In
particular, what is the behavior if there are no ISp devices present?
Also, would the original author like to chase this bug down?
Thanks,
Darrell
