Hi Ben,

Just an update to my previous message.....

I think I got a better understanding of the script now.
I just got all my versions selected out of the database, unassigned them from all categories and assigned only one category: versions.

I then executed the script in the 'fully automatic mode' and it found all masters and assigned them the 'masters' category.

So far so good, with this script I can do what I like to do.

There is one thing left though: when I select a master and ask the script to show me the versions of that master (via accept - free selection - use current selection = 1 image(s)) I still get the message 'Incorrect Versions Selected".

Anything I can do about that?
