BuZz is trying to fix a problem with mousewheel support in the OS3.x build of HivelyTracker, without actually having a wheelmouse. (On OS4, I use the OS4 mousewheel API and on OS3 BuZz uses the newmouse standard.)
It seems that the newmouse stuff sends both a mousewheel up/down event as well as a cursor up/down event. Is there any way to filter out cursor up/down rawkey events generated by the newmouse driver?
