If you are having issues with drivers ona Razer mouse. Check to make sure your driver version wortks with your firmware versuion. If that's OK, reset the mouse (instructions on the Razer site) clear out the firmware, reflash, and reload a clean copy of the drivers. A bad download, or a bad flash can really bork one up. It's scary, but you can reset and reflash. It is safe as long as you follow their directions.
