Hi,
I have created a simple example (Windows 7, Firefox 3.6.6):
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta equiv="Content-type" content="text/html; charset=utf8" />
<link type="text/css" href="jquery.ui.all.css" rel="stylesheet" />
<script type="text/javascript" src="jquery-1.4.2.min.js"></script>
<script type="text/javascript" src="jquery-ui-1.8.2.custom.min.js"></script>
</head>
<body>
example
</body>
</html>
When I open Firebug I have 28 warning messages, either 'error in parsing value', or 'unknown property'.
Two examples:
Error in parsing value for 'filter'. Declaration dropped.
