Mighty Mouse defective?

I have the same Problem

i dont have an answer but my wireless mighty mouse is doing the same thing.

 

Mine used to get a tiny piece of lint in the recess where the optical sensor is. That would make it act all frickin' crazy.

 

I've seen some sporadic behavior on mine, from time to time. A few things to try:

Different trackpad. Some materials track better than others.

Compressed air (can type) on the lens. That's what usually fixes a "jumpy" cursor for me.

Turn the mouse off and on (let the "mouse disconnect" show up).

 

My mighty mouse is doing the same thing, it happens both in Mac OS and Vista. I just ordered a Logitech MX Revolution to replace my mighty mouse so I'll see if this cursor jumping continues with the new mouse.

 

I made a video about this topic on my YouTube channel. Please go watch it!

 

The best answer I found for this (and the only one that ever worked for me) was to flip the MM upside down and depress/roll the little ball around on a clean sheet of white paper. It works every time.

 

The mighty mouse is inherently defective, as it is the worst mouse Apple has ever made. Go buy a nice Logitech or Microsoft mouse.

 

It's far from the worst...
