Hi, I have recently bought a Logitech Optical mouse, and it works great apart from it tends to wonder/bounce around the screen a lot (all desktops or window managers), which if I'm trying to do click on one app, leads me to click on another one, or worse close the current window (depending upon where it feels like going). Has anyone else had these sort of problems, its the same in 8.0 as well as 9, I was hoping it could just be a config change in my XF86Config file, but I'm not sure what to enter, as I cannot find anything on the net about any extra setting for them. cheers in advance Mark
