Peter, i understand your frustration, so let me try and clarify what is
taking place here. What we have is a clash between the ones mental model of
the page and the actual model of the document.

With small document (one that doesn't fill up the browser window) set a
border of a few pixels on the body. This should show what you're dealing
with. The *body* is as wide as the window, but only as tall as it needs to
be. This is often times shorter then the height of the browser window
itself. The minimum height of the document is not the browser height. It's
because of this that centering a box (div) inside of the containing box
(body) would not center it in the "box" that is the browser opening.
Therefore, in reality, CSS doesn't know about the height *or* the width of
the browser, it just happens that the width of the document IS the width of
the browser.

Now, i'll withhold any comments on whether I think this is the right
approach, I will just say that I've seen *a lot* of folks not expecting it
to work this way (or wanting it to work differently).
