I noticed this evening that the function keys on my Macbook pro have stopped working. I can no longer use them to; change volume, change brightness of screen and brightness of the keys. The applications f keys however do still work, so if I hold down 'fn' I can still use the keys as 'F' keys, i.e f2, f3, f4 etc. they just don't work for volume etc. This evening I also uninstalled a program and I'm pretty sure I only wiped the stuff off my Macbook that was related to that program, but the only explanation I can think of for the keys not working is that I accidentally deleted a driver or something for them? Ive searched through loads of forums and no one else seems to have had this problem, selecting the "use all F1, F2, F3 keys as standard function keys" is unrelated to this issue as I can still use the F keys. If anyone can help me in any way it would be much appreciated.
