Standby doesn't work

My Apple TV doesn’t go to sleep. Neither by using the menu nor the remote-command. The light is on all the time and it always display the menu, when I click on Standby in the menu nothing happens. What did I do wrong? Standby worked before installing aTV Flash.

Do you have Overflow installed? If so, please ensure the ‘Settings’ menu is enabled in its default location.

Thx, that solved the problem. Great support!
