after an upgrade from KUbuntu 18.04LTS to 18.10 no spots are displayed in the DX cluster window after a few minutes. The previous spot list "freezes".
The Telnet window is used with "telnet.reversebeacon.net" as "DX-Cluster". After restarting CQRLog, the spot display will work again for a few minutes before freezing again.
Disconnect and reconnect while CQRLog is running do not solve the problem. The login to the DX cluster is executed, but the spot is not displayed.
The problem only seems to affect the Telnet window.
What could be the cause?
Thank you in advance,
