It's just my opinion but I think it's related to the trackball. It offers an opening to the circuit board and one large drop of water is all it takes. I think of the sweaty face (cringe) and the ball touches the sweat, sweat gets it wet and then movement rotates it down right on the circuit board over and over as you move and talk.
