Hello, when I turn SmartMouse off (I have to do that for games), the mouse becomes unusable. If I turn the sensitivity down (Systemcontrol or in game), it gets better, if I turn it up, it gets worse. By unusable I mean: The mouse is flickering and tries to stay in the bottom right corner of the screen. If you move it, it flickers really bad (up to 4 pointers at once all over the screen), but rarely changes position. A way to fix this: Enabling pointer trails. However if those are enabled the mouse becomes invisible if I start a game. Is there any way to fix this problem? Regards DNSYeti
