I have suddenly started getting the following error message, strangely enough when I started using FT4 on 21140 kHz. That might be coincidence though -
"It's my fault, I'm getting old and forgetful
I am about to reset the complex keys in the database and have temporarily lost track of data for your QSO with (whatever callsign) on FT4.
dbBusy flag is set to false
I have not modified your logbook. Please try this again."
