I suspect it is because you have another session open (someone else logged in) Before you attempt shut down again, click on the user applet and see that no one else is logged in. If they are Shutdown and restart will only log you out.
When you are at the login menu Shutdown will not work because you need Super User permissions in order to do that and since your not logged in the option doesnt work.
