title: Appcelerator - barImage hides the title text
body: <p>When I create a new window in Appcelerator I need to change the background image. This is done by setting “barImage”. The window itself is a child of a navigation group and has its own children. When I use the “barImage” parameter it hides the nav bar title text on the initial load of the window. If I navigate to its child window and then back the title text is displayed in the nav bar.</p>
  
  <pre><code>var sectionWindow  = Titanium.UI.createWindow({
      backgroundColor:'#fff',
      fullscreen:false,
      title:’My Sub Page',
      modal:true,
      barImage:'images/nav_bar.png'
  });
  </code></pre>
  
  <p>How can I get the title text to consistently display?</p>
