Screen automatically schrolling down

When ever I'm in Excel, Word, or on the internet reading something, my screen will schroll down without me clicking on the schroll down arrow. I will then have to schroll up and find my position wher I was reading. This is not a big problem, but it is very annoying to me. Can any body help me? Is there something that I need to address in windows or anything like that?

Thanks in advance

 

If you have a wheel mouse, this can happen if there is a problem with the driver. Try updating the driver if that is the case.

 

Thanks!!!!!

Sunny,

Thanks a lot! Not long ago I purchased and wireless microsoft mouse ( Intellipoint 4.1). You would think that it had the lastest version on the disk, but I guess it didn't.

I downloaded the one on the web page and It seems to have done the trick. Thanks a lot!!!!

 

Your welcome. Glad to help.
