jquery $(window).height() is returning the document height
<p>I'm sure there is a simple error I'm making, but I am simply alerting $(window).height() and it is returning the same value as $(document).height().</p>

<p>I am on a 13" MBA and my window height of my browsers when maximised between 780px - 820px (roughly) but each time it is returning a window height identical to that of document height. In every case on the site I am working on it is over 1000px.</p>

<p>What is going on here?</p>

<pre><code>alert($(window).height());
        alert($(document).height()); 
</code></pre>
