Ubu 9.04, all updates installed.
1. Log in as an admin users.
2. Open the User Manager, click the "Unlock" button and enter admin pw.
3. Only me and root show up in list, as expected. However...
4. There is NO "Show all users and groups" checkbox to the left, under the list of users.
When I look at groups, I see all of the groups, but if I try to add a user to a group, I only see me and root.
Any ideas on why this is happening?
