Recently I compiled a 64-bit V120 with QT5. All seems ok but there is one oddity. Every time I start CQRlog, FLRig starts too. This would not be bad as previously I always started CQRlog with a shell script that started FLrig before CQRlog. This was so the frequency from my rig would populate CQRlog. But there is a difference. The old way, with the shell script, all worked immediately. With V120, after CQRlog starts I need to click " Refresh TRX/ROT control" to make the rig freq populate the CRRlog field. Why is FLRig auto-starting when I start CQRlog? I suspect if that did not happen and I used my old shell script all would work as before.
BTW, I earlier built a 32-bit V119 GTK from the files from Saku. That version does not start FLRig automatically. It works just like earlier versions.
