Somehow 'synaptic', 'hardware drivers', and 'software sources' have been removed from the options to use in the System>Admin menu. They used to be there and worked fine. I am running Hardy and using the default login that was created on install. I have previously used 'hardware drivers' for adding nvidia drivers and 'synaptic' for adding programs, as this login, so I know they were there and worked.
I tried right clicking on 'System' and choosing 'Edit Menus'. The editing box opens, Synaptic, etc. are listed under Admin but are in italics and unchecked. If I check their boxes the check shows for a second, then goes away. I tested by unchecking and rechecking something else (Time and Date). When it was unchecked it went to italics but switched back to regular font and stayed selected when I rechecked its box but Synaptic and the others will not stay checked.
