    Erratic scrolling jumping in Windows (Win XP Home 5.1 SP1)

    All window, any application. If the viewable area extends down below or above the set window size the window scrolls randomly (indeed dizzily) jumping up and down.
    Have a wired USB optical mouse with scroll button but I'm not touching it. Have downloaded and installed newest compatible drivers.
    IDEAS? Not even certain this is mouse related.
    It's very hard to work on this way. In fact is even happening as I write this message. ARGH!
    Thanks,

    Kathy,

    Have you checked in Control Panel | Mouse | motion ?
    There are check boxes for mouse Speed and acceleration. You can slow them down a bit to see if things get more to your liking.
    Optical mice can be VERY sensitive. <img src=/S/mouse.gif border=0 alt=mouse width=42 height=33>

    Long ago, there was a time when men cursed and beat on the ground with sticks. It was called witchcraft.
    Today it is called golf!

    Mouse motion set to low and acceleration about midway.
    Mouse is not even touched when this happens. Indeed it happens when my hands are completely off the desk top surface.

    Can you try a different mouse?

    Ita, esto, quidcumque...

    Is it a scroll mouse? Maybe the scroll button has gone haywire internally. I think you can disable the button in the control panel.

    I had a very similar problem; generic USB optical mouse with scroll wheel, that would cause pages to scroll up and down by lines or pages, completely uncontrollable. No Windows or mouse setting would help, and neither did uninstalling & reinstalling the mouse. Then I downloaded the new NVIDIA driver updates from Windows Update, and the mouse problem is gone. I don't know how mouse and video drivers interact, but I'd say that there was a definite cause & effect linkage between the two. Could be worth looking into for your system.
