Okay, just found this one out. Was working and all of a sudden the numeric keypad stopped working. At first I thought it was cause an update failed to upload correctly so I reinstalled that. Still didn't work. Thought I had hit a key on my keyboard, but no the numlock was on and the keypad would light up (normally does this) when I hit a button. I remember now in hindshight that pressing the numbers and my mouse pointer once moved. Stumped and frustrated I finally googled and found the solution:
Numerical keypad doesn't work w/8.04
Seems like there is a bug, still not fixed yet in 10.10 that somehow triggers the accessibility option to allow the keypad to control the mouse. Weird. Go to System -> Preferences -> Assistive Technologies -> Keyboard Accessibility -> Mouse Keys and uncheck the box next to Control Mouse with Keypad.
Uploading ....
