can't type on my macbook 10.6.8
My MacBook won't let me type in any application. I'll try to type and it will take a few letters, then the cursor jumps backwards or everything I've typed will be highlighted and deleted when I continue to type.
I re-installed snow leopard (10.6.8) and tryed zapping the VPRAM twice.
Help?
MacBook, Mac OS X (10.6.8)
