title: Recall last opened file using a sandbox application on OSX
body: <p>I'm submitting my application written using C++ <em>Qt</em> framework and I choose to use sandboxing.</p>
  
  <p>Before sandboxing, my application was able to recall the last opened file stored in the settings. Now I have the following error in the <em>Console</em>:</p>
  
  <pre><code>sandboxd[31386]: ([35064]) Joker(35064) deny file-read-data /Users/martin/Dropbox/DirtyLove/DirtyLove.detx
  </code></pre>
  
  <p>How can I perform this behavior in the sandboxed world?</p>
