I am running Windows XP with SP3 on a 2002 Gateway machine.

For the last few days I have experienced the problem of erratic scrolling that seems to have a mind of its own. If I am on a window with a scroll bar, the window scrolls up and down the page erratically, often when I have not initiated it. I am not sure but think this started following a routine Windows Update. It is doing it now as I type this. It is totally distracting to being able to do anything while it is occurring. It does it a while then there are occasional pauses in the scrolling then it starts up again.

Any suggestions on fixing this?

This question has just been migrated from stackoverflow: There's no need to ask again. – alex Sep 21 '09 at 20:57
He might have misread it as: we closed it here, go ask there ;-) But indeed an exact dupe – Ivo Flipse Sep 21 '09 at 20:59
Sorry, I did not realize it would be migrated over. I reasked the question here after being told it belonged here rather than at stackoverflow. – Jerry Sep 21 '09 at 21:01
No problem. When a question gets migrated all you have to do is press the link where it says "Migrated to..." – alex Sep 21 '09 at 21:12

Sound like your mouse is toast. Try to clean up the wheel (if it has any).
But once a mouse starts to misbehave, it's time for a new one.

I don't believe it is my mouse. This does this when my mouse is not being touched. Any other suggestions? – Jerry Sep 21 '09 at 20:59
same problem with me. do not assume, just DISCONNECT or REPLACE the mouse and see if it makes a difference. – Molly7244 Sep 21 '09 at 21:01
Thanks! I will disconnect the mouse when this occurs again and see what the affect is. – Jerry Sep 21 '09 at 21:03
please do, and then report back :) – Molly7244 Sep 21 '09 at 23:08

I think the problem is your keyboard. One or some of the keys is stuck causing it to do that. Try cleaning the keyboard or plug in a different keyboard and see if that works before you do anything else.

My Microsoft wireless keyboard is the culprit. Unplugging the usb "transmitter" stopped the scrolling.
