Display colorsync profile remains unapplied?

[Christopher Hunt]

Coming to think of it, I don't know if I can say with hand-on-heart  
that display 2 has been assigned the correct profile in non-mirror  
mode... I'll do what Chris suggests and enquire about the profile re.  
Applescript. I'll report back shortly.

Cheers,
