iMac keyboard numeric keypad not responding

Since installing Lion on my 24" iMac, the numeric keypad of my original iMac keyboard does not work anymore. I did reset the PRAM, but that did not do anything. Any suggestions?

Thanks,

Jean F.

Pondini and AMMOCAN were both right for me (on Yosemite)—thank you both SO MUCH:

If the numeric keypad still doesn’t work as you expect, you may have enabled Mouse Keys, which lets you move the pointer with the keypad.
To find the option that turns off Mouse Keys, choose Apple menu > SYSTEM PREFERENCES-->look down at ACCESSIBILITY (same row as Users&Groups)-->Mouse & Trackpad-->Unclick ENABLE MOUSE KEYS
It DOES NOT MATTER if you've clicked OPTIONS and selected a way to Toggle Mouse Keys. Enabling Mouse Keys AT ALL will mess up your number pad.

Same problem: replaced my old simple Apple keyboard with a larger one with numeric keypad. Worked fine on iMac programs but didn't work on windows side. (I am running VM fusion for Quicken, Excel etc.) The default is for the keypad to be turned off. Thanks Tony

Perfect that did the trick!

On my iMac there is NOT a Num Lock Key or a Command +F6 Keystroke.

Also you will find Universal Settings on a newer OS.
