Ok so i've had my Blackberry for ove a year now. Every once and a while the Trackball gets stuck or something and I just roll it around a bit and it goes back to normal. But the other day I got out my Blackberry to unlock it and when i was trying to enter my password it kept hitting enter half way through. It did this untill I got to my 5th attempt and I had to enter Blackberry. So I did a Batter pull. Didnt fix problem. So It made me mad and I just put it away. After messing with it a bit I somehow got it to unlock and it stopped clicking. But now the Trackball is sooooooooo sensitive. If you try and scroll up it hits enter. If you barely even touch it it hits enter. It takes forever to text. Does the trackball just need a cleaning or is it really messed up? I have insurance but you still have to pay $50 or $100 [dont remember]. What now?

-Please Help. Thanks.
