Don't know if there is a cure for this in preferences or if it is a bug. My usual work flow is to copy a disk onto my desktop, then attach my IPTC caption info, then select "view tagged" before I start to edit. About ten days ago, I started to have a problem where as soon as I attached the caption info, all the tags disappear from my selected frames. The tagged frames are still in the folder, but no longer with a tag attached. If I remove the disk and put it back into my camera, the tags are still visible in the viewer in back. This is making editing a nightmare! I have tried with three of my camera bodies, same problem, also tried with a disk from a friend's camera, same problem, so it does not seem to be in the camera. After this happened, I downloaded and installed an updated PM version, but it still is happening. Any ideas?
