Thank you for the responses.

Some encouraging progress!

?

I completed the following steps:

1. I rebooted my machine

2. Changed the performance mode to "best performance" per Jerry's suggestion

3. Started Direwolf

4. Started Paracon

5. Attempted to connect to my KPC3+ pbbs on a different radio

6. Connection completed (I've never been able to get this far!)

7. Sent command to list messages and the message list returned to view in Paracon

8. Sent command to read a message and message contents returned to view in Paracon

9. Sent command to kill a message

10. I get the same error message as before

?

I was able to reproduce the above behavior over 5 reboot and retry cycles.? Direwolf consistently errors after the above steps.

?

Below is the Direwolf log and eventual error:
