I suggest using control.onMouseWheelDown(), control.onMouseWheelUp() and control.scrolldelta() if you can somehow manage to disable the default mousewheel scrolling behavior of the control. I have no idea how you could possibly disable that though, didn't have any similar problems before. I will probably try it when I have some time later today.

Edit: Okay, I played around with that a bit. I couldn't disable the default scroll stuff, and the onMouseWheelDown() and onMouseWheelUp() events don't trigger in the main part of the scroll control. Guess I can't help here.
