Suddenly out of the blue, my razer naga mouse cursor started drifting from the center of the screen towards the lower right corner slowly. The mouse is perfectly still, nothing is touching it at all. I uninstalled the driver, reinstalled the most recent driver i could find for Win7 x64 and also upgraded to the latest firmware avail for the razer naga as well. Still drifts on random occasions. Sometimes it will behave perfectly for days, then all of the sudden, there it goes again, drifts off to the lower right from where ever the cursor is on the screen. I have even tried inserting the cord into other USB ports, still all do the same thing. Anyone else ever seen this before? Ive had the mouse a while and it has always been fine till today. I scanned the system for malware, bugs etc, comes up clean. Any ideas welcome!
