Let’s see whether I am able to explain it
It just happened recently (maybe after last upgrade?) and either whether I choose an station from Cluster or typing manually its callsign
When I type the callsign in Main Window or I choose an station from DxCluster it gets the info from QRZ.com. Sometimes , only happens when choosing station from DX Cluster, the callsign and Name/QTH disappear from the Main Window and you have to choose it again ot typing manually the callsign, sometimes Name/QTH gets empty keeping the callsign so after the QSO you need to add QSO details from QRz.com.
If I type the callsign manually happens the same, as well as if I have typed the callsign manuallyt and I move a bit the frequency to get a better CW tone... the callsign/name/qth get empty...
please let me know which sort of additional information could you need to help you to identify the problem.
It did not happen before as far as I can remember
Thanks
