Lars,
I do have FOC set to scan only local drives. Tried backlevelling the 3 eCoSoft runtimes to the 2017 versions - rebooted - but no change. Classicube still crashes when a file dialog appears, but if I add it to the FOC exception list, it works. Maybe the newer PMEX.DLL is at fault? It does have a build level string:
[C:\os2\dll]bldlevel pmex.dll
