My Yast will not list uninstalled packages

Hi, I have seen a strange thing regarding my Yast in 8.1 now. Yast only lists already installed packages, both in the GUI and ncurses version, and will not show uninstalled packages. If I search for an uninstalled package, e.g. Tuxracer, it do not show, so the only way to get it installed is to fetch it directly from the DVD, which is not too practical. What can be the cause of this? Regards, Jostein
