I had the same problem with writer. I tried all the suggestions above and none worked.
I did some digging around and in '~/.openoffice.org/3/user' found the file 'registrymodifications.xcu'. Looking inside it, it seemed to contains the name of the document I was editing etc. So I renamed it to 'registrymodifications.xcu.old' and restarted writer. Now I can enable and disable the display of invisible characters. I hope someone finds this useful! -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/857041 Title: [Upstream] Nonprinting characters not showing in Writer To manage notifications about this bug go to: https://bugs.launchpad.net/df-libreoffice/+bug/857041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
