I'm having problems hooking up the `mousedown` event for the window using jQuery in IE8. I'm getting no errors, but the event does not seem to be firing. It does work in IE9 and all other browsers I have tried. Here's my code:

```
<html>
<head>
    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.7.1/jquery.min.js" type="text/javascript"></script>
    <script type="text/javascript">
        function test(e) {
            alert('test');
        }

        $(document).ready(function () {
            $(window).mousedown(test);
        });     
    </script>   
</head>
<body>   
</body>
</html>

```
