At least now you have an excuse to get an Optimus Keyboard.

You're not a Dell Dude, are you?
Well i would love it but maybe slightly pricey, as i could buy a new mac for that and still have a bit to spare!
Most certainly not, but its the only keyboard i have been able to get my hands on for the moment now, free of charge
Yep, that's exactly what I did when I thought I'd broken mineIn System Preferences>Universal access>Mouse, make sure that the box "Press the option key 5 times..." is not set. If its enabled, pressing option 5 times will disable the numpad.
Earier I guess pressed the option key 5 times in a row, and it turned the numpad into a cursor controller.
