Help!!
Just downloaded Hardy Heron and updated Gusty Gibbon, but now the following System/Administration programs are not working.

Synaptic Package Manager
Software Sources
Login Window
Hardware Testing

The Starting Administrative Application tab shows at the bottom of the screen and then disappears, nothing else happens.

Also Update Manager does the same when ask to check for updates, and then will not close, only way to close it is to crash. After restarting i get the message Crash Report Detected, i click on it and Starting Administrative Application tab shows and then disappears. All else seems to work.
