5loth: installed Windows 7, has been running fine but now the Function Key appears to be forced on all the tiem so I can't use the keys that have FN numbers on them, tried rebooting but no change.
going to recover to XP to see if it sorts it out. Is a shame as Win 7 was running really well :/
Just the numbers?
Sounds to me like you need to press Fn + Insert (= NumLock) to turn num lock off.
