title: RStudio empty on startup - No windows, no menus, no rendering
body: <p>When I start RStudio, none of the windows inside the main frame come up, and none of the menu options display menu options when clicked.  It's just an blank page.</p>
  
  <p>It feels like some kind of graphics rendering or window management problem.</p>
  
  <p>I'm running Windows 7.  I have the latest version of R, which is 3.1.1.  I have the latest RStudio, which is 98.1062.</p>
  
  <p>How to fix it?</p>
