On my Windows 7, system, in all programs, when I scroll down with my mouse, it will scroll someway down then then scroll someway up. It is totally erratic, and is driving me crazy.
I do have a wireless keyboard/mouse, but I do not use the mouse, as it does not work: I have replaced it with a "wired" mouse.
I have tried adjusting the mouse settings (number of lines to scroll, and turned of "acceleration, I think it was called).
Does anyone know how to fix this?
