i use JTAlert to transfer the log from WSJT-X (last version) to HRDLOG 188.8.131.52 (last freeware version) on Windows 10 64bits.
After a certain number of uploads to the log, JTAlert no longer displays anything in
the windows. No more callsigns appear. I have to stop the JTAlert software and
restart it and it works again.
I suppose there is a bug on JTAlert 2.16.7.
