I bought my iMac at the beginning of March, and already the BT MM scroll won't scroll down. DO you think that I can get a replacement? Or have I just fallen outside of the repair window? I figured it would only last a month (replacement for failed parts). I figured I would take the MM to my local Apple store and see if they can replace it for me. I really don't feel like taking apart the mouse. On the other hand, I am also thinking about getting a logitech to replace the MM. But I want to make sure that the mouse sensitivity isn't so high while playing WoW. Thoughts?
