I'm not an angry person, but every once in awhile computers push me over the edge and I do something rash. And it was such a situation when I hit my trackpad with the tips of my middle and ring finger the other day :\ . Initially, what happened is it would work unless my finger went over the part that I had hit.. then the cursor would lock up. Interestingly enough, the cursor would become unlocked after being put to sleep. But the problems slowly worsened to bring me to where I am now, with a completely non-working trackpad. I've been thinking about opening this thing up to take a look at it. Could I have just knocked something loose? Is it possible to buy replacement trackpads? How does one get at the trackpad in a 12" 1GHz powerbook, anyways?
