title: How can I get a finish button after a nsDialogs page
body: <p>I'm trying to create a post install configuration page in my nsis script using nsDialogs.  My script for gathering the input and executing the configuration works however I'm never presented with a finish/close/exit button after I'm done.  Currently my pages declaration looks like:</p>
  
  <pre><code>Page directory
  Page instfiles
  Page custom nsDialogsPage nsDialogsPageLeave
  </code></pre>
  
  <p>How can I get a finish/exit/done button to show after nsDialogsPageLeave executes?</p>
