Coverflow Wheel scrolling adjustments?

When I scroll through album covers in Coverflow, one "click" of my wheel will skip over two album covers. I can't find an adjustment in itunes. Has anybody ever been concerned about this enough to fix it so that one click brings up the next album?

Ooops. My bad. I adjusted the mouse properties in windows.
