In the old days mice had a roller ball on the bottom which made contact
with X & Y rollers at 90 degrees to each other. The rollers and ball
would collect lint and cause erratic behavior. It was necessary once in
a while to open a plate on the bottom to remove the ball and the debris
inside behind it.
AFAIK, today's mice are all optical. There's a small optical window on
the bottom that emits an infrared beam. I've never had a problem with
an optical mouse but it seems to me that dust/debris could also collect
in the recess on the bottom that contains the optical window. Sliding
the mouse across a surface could jiggle the debris and, I suppose, cause
unpredictable mouse behavior.
Since it's a wired mouse I suppose you could also have a bad electrical
connection on the wire either at the USB connector or inside the mouse.
Hold the mouse still and see if jiggling the wire on either end causes
any motion. It shouldn't.
If you can't find anything obvious give the wired mouse back to whomever
you bought it from. I recommend you replace it with an inexpensive
Logitech M310 wireless mouse

I have 4 of them and they all work fine and have excellent battery
life (one AA battery).

PESO:
My brand new Logitech wired mouse has started jumping all over the place.
I can't do anything with it. I've tried different USB ports but it doesn't
help.
Any ideas what could be wrong?
TIA
