I just bought the new aluminum keyboard. It's great and it feels really comfotable due to the fact that its lower than my previous one. The only problem is that the F12 button does not respond(I use it for opening dashboard). I've enabled the fn key for the characters printed on top of the F1-F12 keys, but the F12 button only works for for volume change. Does anyone else have this problem, and is there a solution for that? Also I had a similar problem on my Macbook pro when ever I would use Aperture, is there a conflict some where?.
