I have the Mighty Mouse and love it. It’s not the wireless version, but the one with the tail connected to the keyboard. Recently, its ball has developed an adversity to upward mobility. That is, I can scroll left, right, down. But not up. I have tried breath control (filling the interior with the moisture of my breath), cleaning with alcohol, throwing into the river, driving over it with my Patton tank. Nothing works.
Question: do I go out and buy another, or is there some way to undo this dilemma?
