I have a Basic Optical Mouse, didn't want an expensive one. But it has fought me since I plugged it in. The mouse will go up-left, and sometimes goes crazy GOING in all DIRECTIONS. I downloaded Microsoft Mouse, but I still have serious issues. This is especially irritating when gaming. What can I do about this?A. That works. Though I thought you were pulling my leg at the time...

B. ROFL!  

I noticed I had problems when I was typing and I watched as my mouse just crawled on it's own to the top-left of the screen. But not anymore. I wonder what makes paper so special...Draw a picture of a cat on your piece of paper & see if you get a REACTION.  Great, now I need another mouse, It went running with it's cord AROUND it's wheel. =/Do you have protection from viruses and Spyware?

[glb]Flame[/glb]Some suggestions:

1. Get the latest drivers, improper or bad drivers can cdefinitely cause this issue.
2. Try the mouse on a different surface.
3. Try the mouse with the lights off, I know sounds strange, but lighting can affect optical mouses.Flame, I have Norton AntiVirus 2005. And it is updated. So yeah, I do.

CH A, Downloading now - Done. It almost finished install when it told me a newer version of IntelliPoint was already installed. And the lights are off. It does it not so often as it used to on the mousepad, and it doesn't do it at all on a certain desk, but I can't move my rig to that desk yet because my wireless signal is too weak there. But I'm going to start another thread about that, it's off-topic here.PS2 seems to work better for mice, if it's a USB mouse you can try an adapter. Quote
