I think I've had similar problems. I too use a serial receiver, and I find
that occasionally my serial receiver gets several steps behind. This has
happened for a very long time, and has happened using the same receiver with
many different versions of lirc and with 2 different computers. Basically,
my remote presses get "queued" up. For example, if it's behind 3 presses
(most common number I've found) and I hit down, left, power, and then ok, the
down, left, and power got queued up. When I hit OK, the down event is
handled. Hitting any button then hits left, another button then sends the
power, and another button then sends the ok. I bet the issue of "seeing" all
the IR traffic may be related, as I've never had the problem occur using my
laptop's irda port as a receiver.
