Trackpad erratic and jumping around

crwdns2893800:0crwdne2893800:0:

Suddenly the mouse of my Macbook Pro started to jump around. The mouse is clicking a lot of stuff out of itself. I tried the following:

- To make sure it is no virus I plugged in a usb mouse which switches of the trackpad.

- According to a lot of forums I had to reset the PRAM/NVRAM, like explained here: http://support.apple.com/kb/PH14222?viewlocale=en_US

- I removed the battery to see if it was swollen. I also tested the mbp without the battery in the body to make sure it was not the battery who caused the problem.

- I removed the trackpad and cleaned it with alcohol.

Nothing helped! What is the next step? The strange thing is that after a PRAM reset the mouse will act normal for about 30 minutes. Then the problem starts acting up again.

Any ideas?
