Mogul application keys quit working

[RickEason]

The application keys on my Sprint Mogul (HTC 6800) quit working today.

The only keys that work on the face/sides are the on/off button, the jog wheel and the center scroll key. The other keys/buttons (such as the mail, internet, ok, phone send, phone end, camera, etc,) do not seem to be working. The keyboard does work.

I have tried resetting the phone.

I have NOT applied the new ROM updates.

Any ideas before I take it in for service?
