Well ... I just tried something ... shut down NX2. Once I did that, had no problems color coding my previously recalcitrant files.
So ... that is a solution of sorts. In previous versions however (including the last Beta before this one), this was not a problem, and it seems a cumbersome fix.
I do have the latest version of NX. Since this only happens some of the time (and not to all files), it is confusing.
