With neither thought nor caution, Filepro List blurted:

I strongly suspect that the processing is not actually pausing, so much as
you're not generating anything INKEY understands, therefore it's still
waiting.
CapsLock and ScreenLock are both scankey-only. They don't actually resolve
to a keysym. The control codes...I would have to do the actual math, but
offhand I'm guessing that mathematically they don't even work out to a
valid character.
F11 and F12 are a bigger mystery to me, as I know someone that used to map
Save to F11, so I know fP knows about it. I can't explain these two away.
Sounds like you're using combinations that filePro is not designed to look
for--mostly invalid control keys and scankey-only keys (caps-lock shouldn't
work any more than shift, alt, or control) that are really modifiers
anyway, not real keys that resolve to a mapping.
