I am new Mac user and I don't really like the Magic Mouse so I reverted to a good old 3 button mouse with a scroll wheel.
When I turn the wheel slowly, it only scrolls pixel per pixel (or per two pixels) If I turn the wheel more quickly, it scrolls nearly line by line. There is a kind of scroll wheel acceleration where the amount scrolled for each wheel step depends on the rotation speed of the wheel.
This behavior is not present in Windows where you always scroll a few lines per wheel step.
Is there a way to disable this behaviour or to tweak it in Mac OS X Lion?
