    Can't access modified pdf files protected by a strategy



      The pdf file is well protected and my students have access to «all the Reader's tools».

      Yet, if they save their work, they can't access their file anymore.

      They get a message stating that since the file had been changed the tools extensions are no longer available.


      I want them to write notes on their files during their exams.

      I want them to be able to save their pdf files and go back to it after a few minutes or hours.


      How do I correct this?
