F18: Sleep at closing the lid, regardless of my current settings

Hi, in Fedora 18, if I set in Power Manager: When on AC, when on battery (both): When closing the lid: Do nothing [My system is localised, so it might be diferent], it still suspends, when I close the lid. Is there any GNOME crap, taht causes this or am I doing something bad? Thanks, Miro Hrončok Jabber: miro(a)hroncok.cz Telefon: +420777974800
