Ok, so I went to the apple support webpage and did all the junk they told me to do, but my might mouse still won't scroll down. It scrolls left, right, and up just fine, but for some reason it won't scroll down. The ball moves fine when i'm trying to scroll down, but, again, nothing happens...anyone have any suggests??? and Yes, i've cleaned it and haven't done anything to it and I can't think of anything I could have done to cause this...
