I can’t really find a proper place to put this so I’ll do it here. I was flying the Leonardo MD-82 on approach to Vienna on VATSIM (P3D v5.2 HF1), latest AIRAC cycle, and I just opened the pop-up FMC to respond to a CPDLC request. Then all of a sudden it just… locked up. With no warning. And then the sim crashed to desktop. I looked at the event viewer and the faulting module name is NavigraphOIDC.dll. I have never encountered this before. Could anyone shed some light as to why this may have happened?
