ok today the mouse ball died again.

This is my work MM, It's lasted quite a while. about 7 months.

I just now tried to scroll up and it wouldn't. I went up and down real fast and its working now.

but….. it's going to keep doing it, and progressively get worse until i give it the clean treatment again.

Not too shabby considering the design flaw of this mouse… at my desk here is not really all that super clean.

That mixed with lunch at my desk every day.
