I've just installed FC3 x86_64 without problems and installed the nvidia driver afterwards. All seems to be working ok but when I started mozilla it appeared that some sections of the screen are not updated properly. When I move the mouse over these areas the gets painted. After that it got worse, now I can not even see the menu entries en most icons wont show up. What can be the problem here? This is with both KDE and GNOME. Is this a nvidia problem or kernel related? I've installed all available updates. Jurgen --
