Hi Kirk,
I have exactly the same problem as orky, except that when I put one of the first two options on the drop down when entering the structured keyword panel from the contact sheet it then opens the panel in the IPTC info dialogue.
I'm on a MacBook Pro Intel Core 2 Duo 2.33Ghz with 2GB of RAM and OS X 10.4.9
This is a bug right?
Best regards,
Theo
