I waited till I saw this wasn't a one-off, but no, after a week it is clear that, every flight, the TGS gauge (the stand alone one, on a second screen) is lit up showing a heading as soon as I unpause FS9 at the very start of things. It used to come on when ATC gave taxi instructions.... but now it is engaged before I have even contacted ATC for clearance. It was fine last week - and I never saw this in PFE. Is there a way to 'clear'/'reset' TGS?
(I also notice BTW that during a flight, the TGS window is often completely white. It does come back in the end, but is that a sign something is amiss?).
Not a HUGE issue (!) but I thought I'd flag it up...
