Thanks Ira. I did see one with my full name one mouse it that was not connected. Don't even remember that one.

The one connectrd now is generic magic mouse I use for emergencies.

I don't see anything else extraneious; so I still don't get this.

Ah... just unmounted a hard drive so I could test the corded mouse in back of the computer and ala, works. Puzzled. My hub is one of the best; expensive, robust; yet now seems to inhibit the mouse.

So think culprit now Hub.. works great until it does not.
