Hopefully it's the mouse, but do keep us up to date. Since it sounds like an environmental frequency to me, I'm afraid if it's not the mouse it will be something you can't control (new cell tower or power lines near your house?). I'd like to be wrong and see you find a solution, though. I may have had one half of one touchstream fail like that, but I don't remember for sure as it has been a long time. Regardless, I believe sensor tests failed on the touchstream. Have you run sensor tests? Also, if you still think it could be static, there are all sorts of static wrist straps available (Cisco hardware always comes with a temporary one, lots of electronics resellers offer permanent ones). Using one should keep you grounded even when you aren' t wresting your wrists, so maybe that's something to try. Presumably one full palm rest would be enough to absorb any static if you were grounded, but doing five to reset the device or unplugging and replugging still might be necessary sometimes.
