I found that last night too. I ended up replacing:

   NSApplicationDelegate --> NSObject
   NSWindowDelegate --> NSObject

in the two declarations. With the change, I successfully built a VM. 
But, the VM behaved in exactly the same way - displaying only a blank 
window. BTW, I noticed there was already code that was commented out, 
which effectively did the same as the above.

My understanding now is that NSApplicationDelegate and NSWindowDelegate 
just provide compile time checks on the implemented protocol, meant to 
formalize a previously informal protocol. So, the underlying 
implementation is somehow dependent on OSX-10.6 behaviour.
