How do I keep my PB from going to sleep when I close the lid? I want to use it as a jukebox when I'm driving across country but I don't want to risk leaving the LCD screen open as the PB rests on the floor of my car. I have searched the settings all over and haven't found a way to do it. The help library isn't doing too much either. I'm pretty sure this is possible because I saw it mentioned in a thread a few weeks back but I don't remember if it was told how to. Thanks for any help.
