Hello friends, I am currently being using the Windows 7 Ultimate of 64 bit. I am having the trouble with the mouse as gets messed every now and then. The cursor turns into a extraordinary line every once and a while, but particularly when playing games with high FPS. If I move my mouse around very rapidly for a small amount of seconds, it goes back to normal. Every once in a while, my mouse pointer gets messed up that is turns into a strange looking line and bar. This seems to occur when I have an only some applications running but couldn't say to you if a particular application seems to be creating the problem. Any suggestion how I can stop this problem? thanks in advance!!
