This happens, at a rough guess, about one in ten times I run PF3. I load the flight plan as normal and connect. Everything looks as it always does, no error messages or the like. But when I come to contact ATC, there is no response to any keyboard input at all. I have PF3 set to give the little 'beep' (I substituted a tiny burst of radio static - sounds more 'lifelike'!) when a keyboard input is received OK. I don't get this when this error occurs. I do get the startup 'PF3 Initializing....' message up on Remote Text though.
I shut down PF3 and load up exactly the same flight plan again and invariably this time PF3 works normally.
This has been happening for a long time, but today I thought I'd post the log to see if you folks can see any reason for it. It may of course be some 'external' problem (i.e. not coming from PF3 itself), but the fact that when I shut down PF3 and restart it with exactly the same inputs and that it always works just fine the second time round, is a bit odd.
Thanks,
Martin
