Hi Ok, this is entirely different. I would have to agree that it is more likely in the keyboard. Nothing much else would cause this problem. Most all of the other moving parts would respond close to the same for the repeat key ( still might be something that is sticky though ). Besides checking the clearence, it might be a good idea to remove the keyboard and watch things while hitting a key. You might see something a little sluggish. You'll need to manually reset it after each keystroke. It is a lot easier to see things when the machine isn't jumping everytime you hit a key. Dwight
