   When using a UIKit object you often run into one of the two problems.
   1. Cocos2d freezing during core-animation or UIKit Scrolling.
   2. Bounce and kinetic scrolling not working in UIkit Objects.

   If you use the threaded director both problems go away,
   [Director setDirectorType:CCDirectorTypeThreadMainLoop]; //For replacing Fast Director
   [Director setDirectorType:CCDirectorTypeNSTime]; //For replacing Default Director
   (it has to be the first call to the director).

   I'm curious whether this will let me use OpenFeint notifications without the performance hit. I'll try it out first thing in the new year. :]

   MainLoop doesn't work with the initial popup screen for OpenFeint in my tests - you can't click the buttons at all, so I have to use NSTimer strictly for that.

   Oddly enough, if I have myself registered on the device already so the initial popup doesn't show, then I can use MainLoop just fine. I can interact with all portions of the OpenFeint UI that is spawned from a button in my menu.

   It's unfortunate because I get approximately twice the frame rate with the fast director ( MainLoop ) that I do otherwise. =(

   Make sure openfeint gets attached to the opengl view.
   [[Director sharedDirector] openGLView], if that doesn't work, openfeint must have some bugs with threading. In that case, I would suggest that you try all 5 directors and determine which gives the best performance for your game.

   [Director setDirectorType:CCDirectorTypeThreadMainLoop];
   [Director setDirectorType:CCDirectorTypeNSTimer];
   [Director setDirectorType:CCDirectorTypeMainLoop];
   [Director setDirectorType:CCDirectorTypeDisplayLink]; //only available on firmware 3.1 or higher
   [Director setDirectorType:CCDirectorTypeDefault];

   I also have a typo, this is the correct command for replacing the regular director.
   [Director setDirectorType:CCDirectorTypeNSTimer];

   I had the same problem. The OF start screen showed no response to any taps. The issue resolved when I switched from fast director to threaded main loop:
   
// [Director useFastDirector];
[Director setDirectorType:CCDirectorTypeThreadMainLoop];

   Threaded main loop works *and* gives better performance than NSTimer - thanks! =D
