Sometimes Fldigi stops working

[PC9T]

I use RUMLogNG now for several weeks with WSJT-X this gives no problem.

But when using Fldigi during contest, the program stops several times sudenly.

RUMLogNG stil working and it's only happening with Fldigi, even with WSJT-X there are no problems.

So it's quite irritating that suddenly Fldigi stops working, and I can't find the solution.

Is this only by me or are there other users that have te same problem.

My MacOS is Catalina, because the many problems with BigSur with Fldigi but even with McAfee, so that's why I did go back to Catalina.

Fldigi crashes have a very long history. Some are more affected than others.
Is somebody here with a connection to the Fldigi makers?

Tom,

Only Fldigi works wit RUMLogNG or are there other programs working with RUMLogNG?
