So, I have an odd situation. My desktop randomly disappears. The icons all go away, and right clicking on it doesn't bring up any menus (the background stays, but I don't think it changes). Also, clicking on the desktop doesn't bring up Finder but if I click on the dock icon, finder works fine. I tried deleting my com.apple.desktop.plist file, but it didn't help besides resetting the background... What else can I do?
