Comment 36 for bug 317025

When I looked into this (years ago), from what I could tell, windows was enabling a different mode of operation in the mouse, one that sent both horizontal and vertical scrolling data to the computer. Linux was using the default mode which translated virticle scrolling to up and down button presses, and horizontal scrolling to tripled up or trippled down button presses. I was unable to do anything with this in hal.
The only thing I have noticed change in the years since I first reported this issue is that more than three buttons became supported on the mouse.
