I have a colleague who is not able to add or edit comments in a PDF. She has Adobe Pro.
If I add a comment with the symbol "T", the comment is automatically "locked" and I can't disable this field.
I re-installed the software, even used the adobe cleaner.
The documents belong to her and I can add stuff, paint stuff in the document, but that's it.
I used this script to activate the comments, but it is (of course) not working, when you want to create new comments.
I still was not able to find a solution. It is a very strange behaviour. The user is now working with "pdfXChange Editor" - no problems.
After running the script right-click one of the comments and select "Make Current Properties Default".
