Hi, I have a set of 23 pics that are duplicated. One is in an album and the same set but duplicated in another. However when I got to delete them I get a message warning about master files, then I press delete the following message appears 'Some versions based on these master files are included in albums outside the project. These versions will be removed from all Albums, Books, Light Tables, Web Pages, Web Journals, and MobileMe Albums'. When I confirm this it deletes both sets of pics, but I only want to delete one! How do I delete one set?? And why is it doing this?
