    I recently got a new iMac. The included Mighty Mouse seems to me to be defective, in that the cursor frequently makes a sudden large jump to another location on the screen.

    That is, I am moving the cursor, when suddenly the cursor jumps quite a distance from where it should be.

    Is this a defect, or am I doing something wrong?

    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.

    The obvious follow up question: how to clean the mighty mouse?

    I was brand new one month ago today. My Microsoft mouse works well and hardly ever needs cleaning.

    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...

    I'll probably just switch the Mighty Mouse with the "nice Microsoft mouse" attached to the Windows box I migrating from.

    Today I finally took a trip past the Genius Bar with the mouse. The tech simply cleaned it of the dog hair, and it worked for him. So this maybe was the problem all along.
