When we password protect PDF in Illustrator the Password protection disappears if we make some changes and just save the file without put in the password again. Same if we open an pdf file with password protection, make changes and just save the file the password disappears. We didn't need to put in password eveytime when we saved the file after put in a password on earlier version. Is this something wrong with the new version or shall it be like this? Please put back old function or make a pop up box that ask for password if the file is password protected.
