Can anybody help... When I go to "User>Login Window..." from the menu bar, my computer just hangs and never reaches the Login Window (it just sits with a bluey-background there and the rainbow wheel...). I've given it a few hours to try and get there, tried logging in and then trying to switch users without loading any other programs, I've even done a fresh install and tried again... Does anyone know what might be causing this problem? And, more importantly, of a solution? When I switch my computer on, it loads the login window without any problems... it's just when I try to go back to it to switch users that it's a problem. I'm running 10.4.11 Thanks in advance.
