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.
