MacBook Pro Trackpad 'Dancing / Erratic Behaviour'
Since a couple of days, my Macbook Pro Trackpad has been behaving erratically. When I try to use it, it sometimes 'dances' around on the screen and does not respond to my touch. When I press hard on the Trackpad, it 'fixes' it and the Trackpad wil work for a short while but will quickly return to its erratic behaviour. What would be the best course of action? Can I do anything myself about it, or should I go to an Apple Store?
Extra Info:
It started after a flight of 2 and a half hours. I have had the laptop with me at all times, and it did not fall. It never did this before the flight.
