The problem is that when I click on the Apple menu in the top left corner, there are multiple entries for shutdown, log off, and sleep. I know it's on the user level, because I created another account and it was fine (no duplicate entries). My question is can I fix this without having to delete my user account and recreate it? Also, randomly there are black lines that outline windows and icons. These lines form a black line border around some of the windows or some part of the windows in finder and the icons on the Desktop.
