This has nothing to do with sailboats and everything to do with trying to use this forum. My mouse moved around on the pad like a cripple. I could drag the little fellow around by his tail and the curser would only follow in fits and starts. So I started picking at the little guy's underside and discovered that there is a little buttom on the bottom that I can turn and the ball falls out revealing two little rollers that were fouled with lint. I cleaned the lint off and the mouse is alive and well again.
