I don't know if anyone of you had encountered this problem. I bought a Logitech Wheel Mouse Special Edition Optical. My XP was able to recognise the mouse as soon as I plug it in the USB port. But I noticed that the pointer often jumps to the corner of the screen. Like for example the mouse is just sitting on the mouse pad (idle). When I move the mouse, it goes immediately to one corner. Also it happens often when I am move the pointer, suddenly it teleports to one of the screen corner. I have to look for the pointer and move the mouse here and there to find it. It's really annoying. Specially when you are on Games and want to use the mouse, it just jumps quickly to one corner. Has anyone had this problem and how to solve it? I 've installed the software taht came with it but no luck.
