No new antennas around.
Receiver is about 6" away. It sits right in front of
the mouse under a shelf.

So... when I turn on the computer, the mouse works
fine. I can leave it sitting there fifteen minutes without
any problem. But after I click my username and put
in my password, that is when I loose control.

Ive unplugged my wireless receiver and tested it out
on this laptop that Im on. I have several computers in
my office, each with a wireless mouse. I have a wired
mouse on my computer and Ill use this wireless mouse
on this laptop for a while to see if there are any issues.

What would I look under in syslog to see if there were
any mouse errors?
