I'm having an issue with the trackpad on my 2009 13" Aluminum Macbook with the large touchpad.

The touchpad freaks out when the button is clicked, and it registers tons of points about the top of the trackpad. The trackpad is sometimes unusable for up to 30 seconds.

It started fairly infrequently, but it has become a very big problem. I'm currently using an external mouse, and when I use the trackpad I'm forced to avoid depressing the pad.

Anyone else experience this? Any ideas?
