Easy enough: stop using wireless devices.  If that's not an option, bring in
some equipment to measure the rfi and see what you can do to reduce it.

I've seen mobile phones and microwaves interfere with such devices as well.
Not always resulting in the same symptoms you saw, but...

 Just to update... I was finally able to catch this in action. It stopped
as soon as I unplugged the wireless keyboard/mouse device from the PC. It
appears that one particular person's wireless mouse is crossing signal with
select others, but none of the nearby mice are the culprit. It still occurs
after the affected devices are reset with the "connect" button on the
kb/mouse receiver. This could get interesting...

Yesterday we had several people complain that their cursor was moving
around on its own, but not erratically or quickly as one would suspect might
be the case of a mouse issue. I used SMS remote tools to watch one person's
screen, and she noted that the way the cursor moved while I was in there
checking things was exactly the same way it was moving before -- it was just
as though someone was actually in there.

Now I can't begin to describe how odd this is -- but I can't seem to find
any common denominator for the folks who experienced this problem (so far,
three or four). Some have wireless mice with a short range and good
batteries with no problems otherwise, whereas the others have standard,
working USB mice. I have seen this before where the language bar was
detecting office and keyboard noise through the microphone as dictated
commands to do thing, but the problem persisted on the first PC after I
disabled it, and I don't think that particular model has a built-in mic. I
checked the event logs and the only person who used the SMS remote control
was me, so I can't imagine that anyone else would have been remoting it
either. So far today I have not heard any more complaints, but nevertheless
I'm still curious yet baffled.

All PCs have updated virus and spyware definitions. Does anyone have ideas
on where to start looking if this problem surfaces again? If it continues
we'll have the corporate chaplain bring in his exorcist buddy.
