IE7 z-index issues

If you have z-index issues, particularly with drop down menus in IE7 this conditional script may help.

<!--[if IE 7]>
	<script type="text/javascript">
		$(document).ready(function(){
			$(function() {
				var zIndexNumber = 1000;
				$('div').each(function() {
					$(this).css('zIndex', zIndexNumber);
					zIndexNumber -= 10;
				});
			});
		})
	</script>
