My understanding of the question is that keydown messages are being
queued and continue to run to exhaustion even after the key is no longer
pressed. I couldn't duplicate that behavior.
The rawkeydown handler below will manage keypresses but won't solve a
backed-up message queue. That's why I asked what the handler looked
like, there may be something there that is causing the behavior.
Or we've all misunderstood the question. :)

If you're using rawkeydown you can check to see if the key is actually

if pkey is among the items of "65361,65362,65363,65364" then

I may be a bit stupid, but as far as I understand you are trying to do
this:
1. You keep an arrow key pressed down,
2. You do other things with other keys while the arrow key is pressed down.
I cannot begin to try to answer your question until you either
confirm what I have written or say that I am wrong and then
explain, clearly, what you want to do.

I have a field with a number in it. when focused, I want the value to go

released.
How can I ensure that message are terminated as soon as arrow key is
released?
What handler are you using? I just did a test with rawKeyDown and
arrowKey and they all stop when I release the key. (Though arrowkey seems
to be ignoring left and right keys in LC 9 for some reason.)
