I'm wondering if anyone else has this happen to them. I have an Apple USB Keyboard which I have been using on my PC for a few months now. Yesterday the left Ctrl, Alt/Option and Apple keys decided to not work, the same for the spacebar. I have tried it on my iBook and those keys do not work on it either. I do suspect my PC has developed a USB power problem (which seems to be from a power surge a few months ago), but the keyboard has been fine until today. Note that I don't want any solutions for my PC problem, but I want to try and fiqure out how to get those keys working again. I have even tried removing and cleaning that bottom row of keys.
