title: ActionBarSherlock spinner not selectable ins ActionBar - Theme related
body: <p>Some users of my application are experiencing a weird problem when using my application in landscape mode. I am using actionbarsherlock and have set the navigation mode to tabs (using ActionBar.NAVIGATION_MODE_TABS). 
  Some users are finding when launching the app in portrait and then rotating the device the actionbar shows a spinner list rather than the tabs (which apparently is expected behaviour). The problem is the spinner is not selectable.</p>
  
  <pre><code>    bar.setNavigationMode(ActionBar.NAVIGATION_MODE_TABS);
      bar.addTab(bar.newTab().setText("Deals").setTabListener(this),false);
      bar.addTab(bar.newTab().setText("Vouchers").setTabListener(this),false);
      bar.addTab(bar.newTab().setText("Freebies").setTabListener(this),false);
  </code></pre>
  
  <p><strong>EDIT</strong> 
  Just discovered it is related to my custom theme. Changing the theme to the default Sherlock.Light makes the spinner selectable. The custom theme is shown below.</p>
