Hi, I have a fairly new Macbook Pro - everything work apart from a few keys. Suddenly my enter/return, zero and command keys stopped working. It happened very suddenly, which makes me think that it has to do with some setting and not dust etc.. I checked and all other keys work just as usually do, it's just the three keys that stopped moving. I cannot figure out why or how to fix it. I hope that someone is familar with the problem. Thank you in advance. David ---------- Bwt, I'm not using a wireless or connected keyboard, but the built-in one.
