no root prompt for gui apps that need it

Just did a network install of Mageia with lxde as my window manager and realized some of the libs i need where only available to Cauldron. After upgrading I can no longer launch any gui apps that need root password because the authentication box doesnt come up. If I manually launch them from a terminal or check the mark to run them in a terminal they work as expected, asking for a password then launching. If I juck click on them nothing happens at all.
