In the end I restarted the PC and tried again. But the same thing. I flew the flight anyway, occasionally swapping frequencies on the COM1 radio to stop PF3 telling me to 'maintain flight level 190'. In the end PF3 came right, but only near to the destination.
Can anyone see why I had this problem. My initial thought was that something (wasn't me!) must have reset some of the PF3 hotkeys, but having checked that, they seem to be the same as ever. (They are not the default ones, as those clash with keyboard shortcuts already in use in the sim; but the ones in the pf3.ini have worked for years without problem).
I attach the logs for both the flights I did, aborted and complete.
Thanks,
Martin
