This is one of those "you gotta see it to believe it" things

A client of mine has the exact mouse that I do. Its a Mouse Systems PS/2 optical type 2544 using the special optical mousepad. Its been working fine until yesterday

He turned the system on yesterday morning and everything was fine. Being a beautiful day, he went out to work in the yard for a couple of hours

When he powered up he immediately noticed a weird mouse problem. Without touching the mouse or the pad, moving his hand over the mouse would cause the mouse pointer to jump around erradically. The closer he moved his hand to the mouse the more the pointer would jump. As he moved his hand away it quit.
The mouse pointer would follow the direction of his hand movements but jump all over.
He tried powering down & reseating the mouse several times. Same problem

His wife came home & had the same problem. She powered down the system, turned it back on & it was fine. When I got there it worked fine.

I am thinking that this has to be caused by some sort of electro-magnetic interference. The problem started after he was in the sun for a couple of hours.

This is really reaching, but is it possible for solar activity, like flares, to affect a mouse?
