title: Intellij IDEA Project view doesn't show structure as it did before.
body: <p>My directory structure in the Project seems to have disappeared. The first picture is the "bad".  I recently upgraded to 12.1 and the vim emulator at about the same time.  I don't know if I missed a dialog that reset something?  I can't figure out how to get it back like the second picture.<br>
  I've tried to re-import the project but it has not helped.  I keep the project on Dropbox and have another PC where I have not reloaded project.  Is there a way to get my view from that machine?</p>

  <p>The picture is the "good" and how I want it to look.<br>
