Thank you for your prompt reply, @PaulWalters. I think I must also be doing something else wrong, though, because even if I do not check the box “Key attribute for selected notes”:
the behavior of the notes in my document remains the same, i.e. all the notes, including Adornments, turn into containers in a matter of seconds. Am I perhaps pasting the DEVONthink item link in the wrong field?
Best regards,
Enrico
