Hey guys, I have a Logitech MX400 Laser mouse. I am also running Windows Vista x64. It seems to be having a really weird precision time with the mouse movement. Sometimes it feels sluggish, like I can't just point at what I want to without compensating a bit. To correct this, I've installed the Logitech software for the mouse, however I didn't notice any improvement. I have been trying to find an even balance with acceleration and mouse speed, and I'm just having a problem in doing so. Are there any known issues regarding this, or any advice? I used another mouse to see if it was me or not, but it definitely seems to be an issue with the mouse.
