I am creating a PDF form that contains several digital signatures. I am selecting a signatures and am in the property options for that specific signature looking at the "Signed" tab. I select, Mark as read only, than choose "Just these Fields.
When I select "pick" a new box opens that lists all the fields in my form with a check box next to each. It appears that I can select the fields I want to mark as read only, however, when I attempt to check a box, nothing. I can select "select all" and all the firlds become checked, but I cannot check individual fields.
Any thought on what might be going on?
