Fldigi 4.2.06.26 on Linux (LMDE 6)


 

Hi again...
?
Pulled and built 4.2.06.26 without issue a few days ago, and everything was good.? A major OS update appeared "took" without issue, and Fldigi still behaved as one would expect, even after restarts and so on.? Great!
?
Fired it all up this morning (March 28th, 10AM UK) and all good.
?
Had to shutdown the PC some time later to move some other hardware about, much easier if I can move the PC and monitors out of the way.? Put it all back and started it all again.? No issue...
?
But, after a while running in the background (while I did some email's in another UI desktop) while it was running PSK31 mode (that WAS showing the AFC control as able to be used, but NOT active.)?? On restoring Fldigi to "the front" (AKA "in focus") and active use, that AFC button is again greyed out.? But, fiddling with the radio and a steady strong signal, the AFC is ACTIVE, but not working correctly, even though the greyed out button shows it as INACTIVE.?? And of course, I can't control it.?? Restarting Fldigi, the PC etc, that AFC button is permanently greyed out, but the underlying AFC functionality is still ACTIVE!..
?
Someone made mention of the fact that AFC was not valid* for all modes.?? Where is that information please?? As I can't see it in the web help doc's.?? Only this, in Fldigi's built in help.
?
AFC (AFC) control

When this button is pressed, an indicator on the button turns yellow, and the program will automatically retune to drifting signals. When the button is again pressed, AFC is off, and the tuning will stay where you leave it.

No mention of which modes it applies to, or not...
?
(* Valid or not, when the control is greyed out, and the LED also shows grey) it seems to be active for all modes, if you watch it's behavior on a busy waterfall, especially a weak signal with stronger ones nearby/encroaching.)
?
So, what on earth is going on?
?
Still confused of Central UK.
