Thanks for the summary.I have only been following it from an informational pov as I cannot even force any such failures. Since the problem has appeared on both platforms, the Design of Experiment I would want to do is one that generates the problem on either/or platforms. So far as Lens Corrections, I use DxO for all my lens/sensor corrections. So for a corrected frame, I have the linear dng of DxO and the original .nef. I can open both simultaneously and apply common corrections but I haven't tried the crop rotate in ACR on either. I reserve crop for PS. One reason is that the working space in PS is much more to my liking, so I do important work there when the unique qualities of ACR are not needed. That being said, I don't see any evidence that Bridge is ruled out, but then I'm not doing the troubleshoot. One question which comes to mind is whether the acquisition of the files from the card has any influence, that is, how do they get uploaded? Here, I use a rather ancient card reader, the default is to use Bridge to upload (or DL, what ever!). There may be some metadata corruption involved in this part of the. process. I have one card which has a micro USB plug-in and I find that to be problematic. In turn, that brigs up a question of the metadata itself from the camera. I have a D80, D90, and D7100. All behave correctly in the acquisition, uploading and behavior in ACR/Bridge.
