I am a new user with PM. I have started editing IPTC fields, working on NEF files and NEF/JPEG sometimes. I have added IPTC info via the stationery pad to a group of photos. However, I see I forgot to check the boxes to add info for certain fields that are written to the XMP format, such as copyright URL, contact address, etc. When I try to add these items by opening one image info and checking them off, then clicking OK, the image closes but when reopened the info has not been added. Also tried adding using the stationery pad to add that info, same problem, the edit does not take. What am I doing wrong? On a mac Intel tower, OSX 10.4.9.
