Just upgraded to Snow leopard. Logged in into my normal user account - I cannot become admin anymore (e.g. click on the authentication lock in system preferences). The authentication window appears and then immediately disappears !
Changing this account to admin doesnt solve the problem - now when I click the lock no dialog appears. very annoying.
