OSX MouseWheel Issues

OSX MouseWheel Issues

Hello,
I have implemented MouseWheel Support for a Vertical iScroll List: 


While this works wonderful on a PC, it totally goes mad on OSX.

If I just touch the MouseWheel of my Logitech AnywhereMX Mouse, some  MouseEvents are being dispatched. And if it turn it one snap (physical snap of the wheel) 3 or more Events get dispatched ?!

If I use a Tochpad on OSX, the momentum scrolling is also preventing a proper usage, 
since multipel MouseWheelEvents get dispatched.

Any idea how I could fix this Issue for OSX Users ?

It would be sad if I would have to disable the Wheel under OSX and provide prev/next Buttons instead.
