I've been having a lot of trouble with my MacBook keyboard since I believe November, and it's becoming more frequent a problem. My question is whether or not it has anything to do with the main problem that's been plaguing MacBooks, or if my MacBook requires a repair visit (which is expensive, since I'm out of warranty): Every so often, for an extended period of time, a "column" of keys are completely unresponsive. In my case, F11, -, normal 0, p, ;, Enter (both Enters, actually), and /. I also get hitched with the first key problem that I've been hearing about. (I should note that I am on Tiger, and will remain so for the next several months primarily due to HD size limitations, and secondarily due to ProTools LE still being incompatible).
