description:scroll wheel makes display jump around.
expected: smooth widening and shortening of display.
actual:erratic jumping around of display as I move the scroll wheel slowly back and forth.
mouse: Microsoft Comfort Optical Mouse 3000 using Intellipoint 7.x software
I am not sure that I understand the problem. Mouse wheel does zooming and I don't see anything "erratic".
it only happens when scrolling very slowly and deliberately. perhaps it's just my mouse or mouse software.
