Need help with resolving AJAX problem...

Hi,

I have the following ajax code (see default.aspx) that's working just fine in all non-production environments, but as soon as I deploy it to Production, I get a javascript error "  'Sys' is undefined " onload of default.aspx. Clicking "yes" to view details about the js error takes me to:

    <script type="text/javascript">
//<![CDATA[
Sys.WebForms.PageRequestManager._initialize('ctl00$CenterMainContent$ScriptManager1', document.getElementById('aspnetForm'));
Sys.WebForms.PageRequestManager.getInstance()._updateControls([], [], [], 90);
//]]>
    </script>

Both environments are using .net 3.5 and have AJAX extensions installed. Both web configs have the lines:
      <add verb="*" path="*_AppService.axd" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" />
      <add verb="GET,HEAD" path="ScriptResource.axd" type="System.Web.Handlers.ScriptResourceHandler, System.Web.Extensions, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31BF3856AD364E35" validate="false" />
      <add verb="*" path="*.asmx" validate="false" type="System.Web.Script.Services.ScriptHandlerFactory, System.Web.Extensions, Version=1.0.61025.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" />

Can someone please tell me how to solve this?
Thanks a bunch.
