"NULL after navigation" could be clearer - it suggests that DOMWindow 
and everything below it only exists if you type the URL, but not if a 
page is loaded by clicking a link, which can't be true.  Does it mean 
that it's NULL immediately after navigation, while waiting for the load, 
and is replaced by a valid pointer after loading?
