Some IR receivers have been confused by compact florescent lamps - the
electronic ballasts on some lamps run close enough to the 38KHz carrier
used by remotes that the receivers see lamp flicker.

If you are getting keypresses when nobody is using a remote, try
completely covering the IR receiver - upside down coffee cup or
whatever.  If the problem goes away, it was caused by IR light from
something, NOT by software.  If it persists, then the problem is elsewhere.
