My wife and I recently purchased a new MacBook. When I am logged in under my user ID I have no problems with the Mail App, but my wife does. When she is ready to log off the computer she will go to | Apple | Log Out "Name" | and then nothing happens. Eventually she needs to go | Apple | Force Quit | and then Force Quit Mail. The computer then immediately logs her off. Any idea how to fix this other than deleting her user ID and creating a new one? Thanks!
