My problem is that when I am viewing a page on my monitor - it can be a web page, spreadsheet, word document etc, it scrolls further down the page by itself. If I scroll it back up it will often just move me back down again. As you can imagine, this can be very annoying if you are reading or working on a specific part of the page. I've had this problem for approx. 3 months now. I have an Athlon 2000MHz processor, 256 Mb memory, 80 Gb hard drive, Windows XP, and no unusual software that I can think of.
