I don't know what it is, but Zen ALWAYS wants to rotate into landscape mode when I'm at my homescreens. I have a widget to shut-off autorotate and even made sure it's off in the settings and yet Zen won't quit. It won't rotate if I'm playing a game or using the internet, but in the homescreens it will and it's utterly obnoxious. Anyway to stop it for good?
