That's strange, because as far as I can tell, it works just fine for me.

It's not very pretty but I think I needed that in order to jump out from 
case ButtonPress before entering ButtonRelease if either of buttons 4 
and 5 were pressed.

Like I said, it's not very pretty and someone else, being less tired and 
confused, could probably improve it.
