Please learn to quote (to *post*, really).  Full-quoting the entire text 
(including the signature) and adding your answers all below that is not 
appropriate.  You have been referred to the FAQ of this newsgroup already.  
Further disregard of this most basic rule of posting will result in your 
postings being ignored by me.  Free time and other resources are too 
precious to be wasted like this.

Wrong on all accounts.

First, it does matter that you use `window' because when you do that you are 
not relying on the global object having been augmented by the host 
environment with an `alert' property (only a `window' property), or on the 
host environment providing the necessary scope chain (in event-handler 
attribute values).  Keep in mind that host environments differ from one 
another as the ECMAScript implementations they support differ from one 
another.

Second, the object referred to by the `document' property is not involved 
here.  That argument may in itself be valid (tests are pending), but in this 
context it is a fallacy.

Third, you are _not_ calling anything then; `document' is a property access 
(implicitly, by identifier resolution along the scope chain), not a 
(function) call.  Mind your terminology unless you want to be written off as 
a hopeless script-kiddie.
