Weird happenings loading gigapan DNG files processed by DXO or PS ACR

I"m taking my raw files, running them through DXO or PS ACR, doing vignetting correction.  However, using DNG files for this it seems like the vignette correction is being "lost".  I can view the modified files and they look fine, but once into APG - I have the dark edges again.  Is this even possible? 

Saving to Tif, then to APG works, so it seems I'm having some sort of cross-application weirdness with DNG files.  I'm pretty sure this used to work.

I'm running Mac 3.0.0 beta 3

tnx

It's possible that DXO corrections made on DNG are saved with something like correction profiles. So these corrections have to be applied on DNG reading.
Saving into tif format is a good workflow. It makes sure that correction set by DXO are done by DXO. And with tif 16bit format you will have no loss of quality.

Re: Weird happenings loading gigapan DNG files processed by DXO or PS ACR

Ok, some sort of weird operator error, well two.   I reran a sample pano, tiff and dng - and everything works.    This was coupled with me not being able to get DXO to "work right", but in the end I figured out that I shot a pano with a polarizer attached (instead of my UV filter) which completely screwed up the vignette calibration.  I did a full test run yesterday and, of course, everything works fine.
