but since this is a wireless mouse, is there a wireless receiver close by? If so, make sure nothing is interfering with the signal. I find 'line of sight' is best, even though mine is wireless as well.
Do you have a wireless land-line phone near by? I've heard that these wireless phone sets sometimes interfere with wireless computer components as well, although never a problem for me.

I have a Logitech MX 1100 wireless mouse that replaces a Microsoft Intellimouse 3.0 . The mouse was slowly going bad, hence why I got a new one...otherwise that mouse was great.
Anyway, after a while of usage, the mouse starts to exhibit skipping problems. As more time passes, the skips get worse to a point. The mouse has disconnected one me once. When I unplug and replug the mouse in, then the mouse is back to its normal accurate self. Then the whole issue starts over again.
I dunno what's going on. I tried different USB ports but no change in behavior. Got the latest drivers but no help. I've read that other users have had similar issues like mine, except theirs get disconnected completely. No one has posted a proper solution.
Does anyone here know how to fix this problem?
