No, most other scenes seem to load as normal.  I have reinstalled the offending scene (First Class Cabin from DAZ) without any improvement.  I am beginning to wonder if the relatively quick openings where second tries, when textures remained loaded in memory.  Perhaps this particular scene simply takes over 10 minutes to load.
