title: Interface Builder: I can't change names of my objects in the list since I updated
body: <p>I just updated Xcode to the latest version 4.2. Only problem is that when I go into Interface Builder I can't change my objects names in the list of objects on the left. I used to be able to click on them twice or mark one and then press enter to change it. But that doesn't work anymore. </p>
  
  <p>Any ideas would be appreciated </p>
  
  <p>Thanks ind advance :)</p>
