Problems accessing webservice usign IIS7 & Vista

Hi there,

 My code worked fine before (ajax beta 2), and now I've moved to Vista & IIS7 and having problems. (p.s. I've already turned on the classic application pool)
I beleive that the webservice is not being serialised to the client properly

Here's sample code:

 <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Default.aspx.cs" Inherits="_Default" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.1//EN" "http://www.w3.org/TR/xhtml11/DTD/xhtml11.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title>Untitled Page</title>
</head>
<body>

<script type="text/javascript">
    function test()
    {
   
      &nbs ...
