So my Logitech MX1000 Laser Mouse starts to act funny.....I can make the cursor move from side to side but not up and down. Did all the usual things (reconnect the blue tooth, check for full battery charge, reposition the blue tooth hub etc) but no good. Finally I took a small piece of tissue paper and used a toothpick to clean the lens....Now it works perfectly again. I must have had something on the lens but when I looked I didn't see anything. Just a heads up in case somebody else runs into the same problem.
