I don't know what can be causing this. I tried restarting it but as soon as I get my desktop loaded and I click on an icon it starts scrolling down again. I try my best and finally open FF and go to bookmarks and it scrolls down there also. Same with the start menu, right click and program list. Now I can't open anything because it scrolls down to the bottom before I can even click on it. I'm on my PS3 typing this up. What could be causing the downward scrolling?
