Screen Saver returns to default
I use system prefs to change my screen saver to be an album in my photo library, which is located on an external hard drive. This works just fine, until several hours later the screen saver returns to being the national geographic set of pictures, which I surmise is the default.
Is this because my photo library is on an external drive?
