I have been updating a lot of actor's details with photos. I have found when in the Edit Actors Details Screen if I click the Paste From Clipboard button the photo appears, but, when I return to the film's details the photo is not shown. If I return to the Actor's details the photo seems to have disappeared. If I go into the Actor's Cover Manager the missing photo is there. If I then click Paste From Clipboard it adds another copy of the photo which works correctly.
Paste From Clipboard only works correctly for an actor from within The Cover Manager
