title: After changing AppDelegate to Objective-C++, can't addSubview to UIWindow anymore
body: <p>After adding OpenFeintX, I had to change my AppDelegate to (.mm). Not sure f this is absolutely the reason of the issue but it seems like the only thing that changed. </p>
  
  <p>Now, anything that I addSubview to the UIWindow doesn't actually show. If I put a video, it still plays but shows nothing.</p>
  
  <p>Any ideas?</p>
