I tried that....after I did that the cursor wouldn't scroll down at all for like an hour and then finally started working again(what I mean by working is barely working...I'll have to roll the ball downward like three times to get the cursor to move downward). This only happens in the down direction. I am using the new OS that I just upgraded a few days ago.
