I just successfully installed Leopard 10.5 on my Quicksilver 933mhz, but now I have a new issue, when I try to open/change to a new screen saver I get this message: " Cant load screen saver. Screen saver ."Mac" did not load properly. Please select another. Error-cant load bundle. I tried to change to other screen savers but get the same message on all of them. The only one I get is "Flurry". I hate Flurry! What should I do..??
