Hi!
I wrote unusable because the entry of the OAT is quite vital for the calculation of the correct EPR setting. And there we are with a 100% "working" trigger for me:
Everytime, really every single time, when I press the CLR key with the OAT Celsius or OAT Fahrenheit field being selected, my FSX crashes.
I could do a flight without touching the PDCS at all, but that shouldn't be the solution, right?
Greets,
Michael
