title: Unable to open files in octave GUI
body: <p>I've updated to octave <code>4.1.0+</code> on my mac via homebrew. </p>
  
  <p>Two (related?) problems that I'm seeing:</p>
  
  <ul>
  <li>Now when I type <code>octave</code> on a command line the Octave GUI opens fine, but I don't seem to be able to open any files (<code>.m</code> or otherwise). When I double-click a file nothing seems to happen, and there are no messages on the command line window, even if I use the <code>--verbose</code> switch to start it up. </li>
  <li>When I try to close the GUI's window, octave just blocks, and the only way I can get it to close is to kill the process on a command line.</li>
  </ul>
  
  <p><strong>How can I debug this to understand what's going on?</strong></p>
