This started after the last update to 3.7.1. Everything works fine, takeoff, vectoring and the initial climb. A repeating CTD happens every time I'm getting the message to climb to my final altitude FL380 (from FL360). I have tried without PF3. Here everything runs smoothly. I can't find the error, perhaps you have an idea.
Prep3D V4.1 (latest update)
KLAX-KSEA (both payware and P3Dv4 compatible)
iFly 747-400 (P3Dv4 compatible. PF3 setting: FO fly via AP - when I write this, I think I will try to change the setting so I handle everything).
Windows 10 (fully updated)
ORBX, FTX Vector, North America LC
Later tonight I will try again with PF3 with new settings, but any comment on the issue will be appreciated.
