hi, just wondering if anyone has had similiar problems or knows any optimal settings for better performance

I bought a wireless keyboard/optical mouse the other day along with surround sound system(subwoofer, speakers, soundchannel, etc)
everything is working great except.......the mouse is getting on my nerves! Maybe it has something to with interference to the receiver or something but sometimes it moves offscreen and i have to pick the mouse up to get the cursor back That isn't the worst of it though.....this is the main problem i want solved....while im playing CS my mouse will all of a sudden go straight up and start me spinning in circles...or go straight down and start spinning!

As you can imagine this can create problems during a game..

Any help would be much appreciated
