Sticky Mouse on Screensaver Awakening


Helpless Mac Newbie
I use a trackpad on a new powerbook. When I deactivate the screensaver, through moving my mouse or a keypad touch, the mouse wont move. I'll move my finger all over the trackpad, but the mouse is stuck. Sometimes it unsticks after 15-20 seconds, or sometimes I have to toggle the dashboard or another program to get the mouse moving again. What gives?

I'd like to add that I've used the search function on this forum and found this question asked multiple times, but with no sufficient answer yet. Dont just do this for me, do this for everyone in the future.
