The Fn keys don't seem to work on my Macbook Pro when it's runnign windows 7 Under bootcamp. I can't turn the volume up or down or mute the sound etc.
I've found articles leading to me to believe that I can do this using the bootcamp entry in control panels but I've had no luck doing this. all it seems to change is whether I have to press the Fn button to get the normal behaviour of the F keys. E.G. whether I have to press Fn and F5 to refresh the page of just F5.
I think there is a driver issue with Windows 7 as people seem to have gotten them to work under XP.
