Repairing the Mighty Mouse

Speaking of MM, be sure to check out SteerMouse: http://plentycom.jp/en/steermouse/ Much more control for remapping buttons/scroll actions. Be sure to check out the About SteerMouse screen and the Analyze Device option if you like reading hex and figuring out what it means...

I thougt part of the joy of an optical mouse was you didnt have to clean it out every couple months. Why didn't they just the top optical too? That would have been real neat...

I had lots of trouble with the mouse jumping. It did not require taking apart the mouse to fix. It turns out that the optical system is sensitive to large changes. I was using a fake woodgrain top desk, and that was too much change. I am now using a mousepad with little variation in brightness and color. It works fine.

The rollerball is on top. It's used for scrolling :)

I'm sure this is a foolish question, but if this is an optical mouse, how does stuff get inside? There's no roller ball to pick up gook from your desk and transfer it ...

It IS quite easy to disassemble the mouse actually, just push your way between the side buttons and the mouse, then take the ring off, and you're ready to clean the whole thing out.
