The last two PDFs I've saved (vXI 11.0.03, OSX ML) with my standard security settings--no changes allowed, printing and everything else allowed, no password required to open or download--have somehow become locked. The file appears with a padlock icon instead of its cover page facsimile. Users of Mac browsers and tablet/phone devices are either unable to download the files without a password or unable to open the file if download completes. Interestingly, users of Windows browsers don't experience download or open issues.
On checking, I found that security is set to conditions other than what I actually set when saving the files. If it had happened once, I'd say "user error" and be done with it. Happening twice makes that very unlikely. Is something going on with security settings in Acrobat XI?
Thanks,
Karen
