title: jQuery event.pageX/pageY inconsistent in firefox/ie
body: <p>In trying to convert some of my JS to cross-browser compatibility, I've come across strange behaviour where I'm unable pinpoint the problem.</p>
  
  <p>I want to convert window.event.x (IE specific) using jQuery, so my code looks as follows:</p>
  
  <pre><code>function someFunction(e){
     var ev = $.event.fix(e);
     alert(ev.pageX);
  }
  </code></pre>
  
  <p>This returns the correct value in IE, however in FF it's returning an <strong>eight-digit number</strong>. Any clues?</p>
