I have a love-hate relationship with this stupid thing. When it works, it's heaven. But the stupid scroll ball gets all messed up and won't scroll down. I clean it, rub it, blow it out, use rubbing alcohol, it works for minutes, sometimes hours, then gets all clogged up. It seems sometimes I can get it to work great for a few hours, then I leave and come back the next day, and it stops fucking working again. Is there a way to actually get this thing clean. It's like I get the sensor clean, but the dirt is still inside the cavity and ends up back on the sensor. It is one of the very first mighty mice, I don't know if they have gotten easier to maintain or what. Anyone else share in my frustration?
