O.K., I think my might mouse has finally had it. I tried all the tricks that have been talked about in the forums where you clean the scroll wheel, blow it out, shake it upside down, and throw it up against the wall (those are all true except the last one of course). None of the tricks are working anymore, it just simply won't scroll down. Does anyone know if applecare will take care of this, or does apple consider the mighty mouse a perishable item?
