I have a relatively new powerbook (since ~May) that is giving me some difficulty.
I'll be in the middle of doing something and all of a sudden the keyboard will lock up.
Regular typing ceases to work and none of the function keys do anything either, although
using the mouse and drop -down menus does continue to work properly.
The problem is really annoying because it happens every couple of minutes. The keyboard
eventually starts working again after pressing some keys on the keyboard repeatedly.
Any ideas what is causing it to lock up?
