OS X: Photoshop not posting thumbnail previews in Finder or metadata for Preview...?

[Gotta Dance]

Hi Everybody,

I work in ad production builds and QA is a big part of what I do. Right now Photoshop is not functioning properly. When I save certain files it's not posting a preview thumbnail, nor is it providing any metadata or details of the PSD. 

I've checked Preview Options in Finder (Icon Preview only toggles for some).

I've checked 8 vs 16-bit. (as you can't save to BMP with 16)
I've checked Color Profile, nothing seems different

I tried the whole Activity Monitor cancel "com.apple.quicklook.ThumbnailsAgent" bit...it doesn't help.

What's annoying is the some images work and some don't. I can't tell for the life of me why one does and one doesn't. 

Has anybody had trouble with this at all? Does anybody know why this might be happening? It would really be nice to see the PSD previews of my thumbnailes.

I did recently make a small discovery. I'm not sure why, but turning off "Save As" legacy in Prefs>File Handling has turned back on the thumbnail preview action upon Save. So there's something with "Save As" legacy that sucks.

I initially did this because Adobe did the awfult thing of not allowing double-clicking Enter to auto-save over files in Save-To-Web. I persistently have to reach for the mouse and select "Yes, I want to save over the thing". ...100 times a day. I found out recently that's just a Mac OS Finder thing. I so wish they would remove that, and just let me double click Enter to save over images. CMD-R is a weak altternative.

And if you instead, save it as a TIFF?
