Strange behavior with Camera Raw 10.2
Using Camera Raw 10.2 with Windows 10. I loaded 8 DNG files into Camera Raw and highlighted all 8 and applied the Auto adjustment to them. That adjustment was applied to all 8 images. After applying that adjustment, subsequent adjustments would only apply to the topmost image. This anomaly was brought to my attention by a user who posted the same issue in the Adobe camera raw forum.
