Bill,
As stated in my post, replaying .wav files that where saved during
when the original failure occurred does NOT cause the failure to recur.
Also note that while WSJT-X is in the fault mode, ALT-Z only clears
the indicator until the next time the decoder is supposed to run (~ 12
sec ). And then the decode indicator stays on again.

From time to time, usually while monitoring 6m over night, I get a a
Decode lockup. The Decode button is ON continuously, wide graph is
still running, wav files still being saved and no decodes are
displayed in the band activity window. Seems more frequent with 2.2.1
than 2.1.2.
Stopping and restarting WSJT will clear the issue. Replaying .wav
files for the time when the lock up occurred does not induce a lockup.
When the lock up occurs, an 'Erase Band activity' will result in a
brief pause in the highlight button being ON ( i.e. at about 12
seconds into the cycle, the button toggles off for about 1 second,
and then back on until the next 12 second epoch. )
If I issue a ALT-Z at the beginning of a cycle, the decode indicator
goes off until the next 12 sec epoch and then stays on. If I pause
decodes by turning off the monitor, issue a ALT-Z and playback a
.wav file, the decode indicator comes on immediately and stays on.
( Even with .wav files that playback correctly after WSJT has been
restarted. )
Once locked up, changing the decode depth has no effect on recovery
attempts.
If you have addition debugging trials.....

Hi Al,
if you can provide a .WAV file or minimal sequence of .WAV files that
can reproduce this issue when playing them back in WSJT-X, then please
provide them.
The FT8 decoder can be "unfrozen" by hitting the Alt+Z key when this
as yet undiagnosed issue occurs. See "Menu->Help->Shortcut keys" for a
reminder.
