Hi Kirk,
these are really, really terrible news because cropping in PM is a fundamental part of my workflow. I had the hope to simply write a script for exiftool to change the namespace back into ACR, but this idea is now not feasable when you do any PM specific calculations as you wrote.
So, do you see any chance (PLEASE, PLEASE, PLEASE) to send me a link to a version where cropping is still working. To be honest, I didn't mentioned any bugs or big problems (in the parts of the program that I'm using), so I could live with the mentioned bugs in such a version.
Thanks in advance,
Lars
