VarAC appeared to be hung up. The Connect to and Connect station selections were grayed out. The Send Beacon selection was flashing Send Beacon soon.
I clicked the VarAC disconnect and abort buttons--noe effect. I disconnected VARA-HF and reconnected VARA-hf--issue solved.

Yes I see the problem.
You tried to disconnect... and then clicked the ABORT.
VarAC never received a "DISCONNECTED" message from VARA-HF so it was hang in a unknown state. QSO ended but did not receive a confirmation for that.

Tried to simulate but was not able to. in all my tests VARA-HF sent a good DISCONNECT message.
it can be a glitch with VARA-HF but I'll keep an eye on this.
If it happens again please let me know.
