Hi Chris,
If I turn that option on, I get the type of icons shown above in my third post of this topic out of CC. That is, they have a white border around them. Is this the new "normal", or should that border not be there if the icons are being displayed correctly?
Here's something you may also be able to answer. Back in Snow Leopard, Apple announced they were doing away with Type and Creator codes, replacing them with Uniform Type Identifiers. The OS, even now under ML, will still read these old resource fork codes, but none of the apps Apple writes will create them. Most newer apps don't, either. I was also informed by a developer that it won't be long (maybe with OS 11), that the Mac OS will be a 64 bit OS only. 32 bit apps won't even launch. It's an elimination of the need to handle two types of memory management at the same time.
So the question is - is Apple working their way to the elimination of the resource fork altogether and heading towards a single data structure (I've also read they're working on doing away with the now ancient HFS file system). I completely understand if Adobe is under an NDA and you can't answer, even if you know. In which case, you could still say, "The answer might be yes, no, or maybe." 
That is the new "normal" - since that is how Apple wants to display them.
Apple has marked the resource manager routines as "deprecated" in their public API headers, but has made no announcement on when they might go away.
