Changing group works for me in Ubuntu Jaunty. I select Documents and press Properties > Permissions. I change the group to, say, 'CDROM' and file access to 'Read-only'. Pressing 'Apply permissions to enclosed files' will change the file access permissions for all my documents for the group CDROM to 'Read-only'.
Is there something I'm missing? How can I reproduce what you are experiencing?
