Ive been using this mouse for about 4 months now and everything was fine until one day the scrollwheel stopped working. Middle button works okay. First I thought that something broke inside or something like that. But when looking thru CUE I noticed that if I force update my mouse firmware it works for ONE scroll only. Same goes after a restart. I can scroll once, thats it, stops working afterwards. Tried different ports, reinstalling CUE, updating. Nothing works. Any Ideas?
