i am running mac os x 10.5x leopard. i download wallpapers and store them in a folder called my wallpapers in the pictures folder. when i go into system preferences, then desktop and screen saver, and then desktop, i click on the + sign to add my "my wallpapers" folder to the list. but it adds another aperture projects entry. so now i have an entry for apple, with apple images, nature, plants, black & white, abstract, solid color and pictures folder, and then two entries for aperture projects. i can expand one of the aperture projects, but trying to expand the other one does nothing. this has happened to me before. does anyone else have this problem? what com.apple file do i need to delete to reset the settings in the desktop sys pref? at least that way i can get rid of the second aperture projects that does nothing.
