My USB keyboard does this as well once in a while. I've just gotten so used
to USB quirks that I just reboot and move on. I did just try Tom's
suggestion. What the heck. My experience is that USB can be quite fickle
from time to time and I live with them, but beats serial or parallel
connections!

If the keyboard is connected via USB, turning off the USB power
management might help. Start/Control Panel/System/Hardware/USB Root Hub
(properties)/Power Management - uncheck block allowing USB to turn off
(do this for each Hub). This feature is intended for periods of
inactivity, but it MIGHT be malfunctioning.

reboot the machine. I have been unable to figure out if it is related to a
specific program or not, as I said it doesn't happen very often.
