If I delete a plist file, is everything supposed to go back to default options? For example, I just deleted my com.apple.systempreferences.plist to resolve some issues with my screen saver. I thought from what i had read previously, that my screen saver/desktop/energy saver/etc would default back to system settings. However, it appears to have restored to the settings I had created. That's great! I was just wondering if that is common for these .plist files.
