How can I unstick my trackpad button? The trackpad button on my 2007 Macbook Pro seems to be sticking.  Specifically, it's stuck in the "down" position, which means I'm selecting pretty much everything all the time (you wouldn't believe how frustrating it was just to ask this question).  It was fine yesterday.  What can I do to unstick it?
The trackpad getting stuck is also a well known symptom of a bulging battery in the MacBook Pros of this generation. I'm dealing with this issue myself and am very annoyed about it too, because this 2007 Santa Rosa MBP I paid for is essentially the most lemon computer I've ever owned (at least four other hardware failures besides this one).
