left/right arrow keys not working

[gquant]

Hello,
Just did a fresh install of maverick and out of the blue the left and right arrow keys are no longer working. the arrows on the numerical pad work.
Any suggestions/ideas?

thanks

Does activating the NumLock fix this?

Nope, if NumLock is activated I have no left/right arrows at all.
thanks
