My main day to day mouse has been a Logitech MX revolution, it's perfect for what i need, But ever since I picked up a new imac about 3 weeks back I have noticed that the mouse has issues tracking and starts to lag from time to time. I never had these issues on my macbook and still dont, only the imac. I have not changed the location of the mouse, have not changed mouse pads, and have no changed locations of the USB dongle. My magic mouse works perfectly, So I have resorted to using that for the time being, but it Just isn't the right mouse for my 10+ hours a day at my computer. Any thoughts on what could be causing this?
