I bought the Logitech MX 700 a year or two ago and I had a problem with cursor jumping around and at times scrolling in the wrong direction. I stopped using it after a few weeks but I decided to give it another try after getting a new putter. Two days later and the problems are back again intermittently. I'm using XP pro. Anyone have an idea what’s going on. Thanks Moodylink aka Lesley
