If you have a newer Microsoft keyboard you probably know what I mean... its that damn "F Lock" key, where the function keys (F1, F2 and so on) don't work like normal function keys until the F Lock key is pressed. This has driven me crazy ever since I got my wireless keyboard.

Anyway, there is a registry patch to reverse this behaviour, check out http://www.mvps.org/jtsang/flock-e.html to get the registry patch.
