I use my numeric keypad for its intended purpose: entering numbers. My boss, on the other hand, doesn't believe in the arrow keys (or something), so whenever he uses my computer, he turns off my numlock.
I find this quite annoying (<--understatement), and I've often wondered if there was a way to either prevent him from messing with my keyboard settings, or resetting it after a period of time, or something. Even a simple confirmation message ("Are you sure you want to misappropriate the numeric keypad? Do you know that there's a perfectly serviceable delete key just a little bit to the left?") would help.
Is there a program that will do this? (OS is Windows XP, at least for now; might be Windows 7 in a few weeks.) Failing that, is there some place that sells a gadget that will give my boss an electric shock if he touches my numlock key?
