I flagged your other letter to “read it in depth later” but will then  
drop that :)

It did sound like retain-cycle related. If your controller retains a  
view, that view in turn holds a pointer to its superview a.s.o. until  
it reaches the window, so indirectly your controller retains the  
window (I think, not 100% sure).
