Hi all,I've been flying the PMDG Boeing 737-600/700 for quite a while now. But today I flew the Boeing 737-600 Air Europe for the first time on IVAO. Everything goes exactly as planned, taxi, takeoff, climb. But that's where the problems begin. I set my CRZ ALT @ FL270, and the plane climbs to this altitude and levels off (VNAV). But then the FMC says: VNAV DISCONNECT/UNABLE CRZ ALT, and deletes al the speeds and altitudes from the LEGS page. But the aircarft is already at it's cruising altitude, so why does the FMC do this? I've never had this problem before. Who knows the answer to my problem?Thanks in advance!Michael "Flightfreak" Henke

A little add to my post.This is my flightplan: LEPA MEROS UN853 LUMAS UT16 AGDOR UN870 MAXIR UY46 LUC LFMN.Michael "Flightfreak" Henke
