AJAX hovermenuextender doesn't work with radscriptmanager

[Gabe]

I'm developing a .NET 4.0 site in VS2010, running in IIS7.5 environment.Every forum I check says that my version of Telerik RadControls for ASP.NET AJAX (V.2012.1.411.40) should play nicely with the AjaxControlToolkit elements. My Toolkit version is 4.1.7.1213.I've tried to use RadScriptManager, but it blows up when it tries to `$create` the HoverMenuExtender control (at runtime) that I use within the RadGrid:
   

<telerik:RadScriptManager ID="RadScriptManager1" runat="server" EnableScriptCombine="false" >
    <scripts>
    <%--Needed for JavaScript IntelliSense in VS2010--%>
<asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" /><br>            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" /><br>            <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
</Scripts>
</telerik:RadScriptManager>

HoverMenuExtender inside RadGrid:   

<ajaxToolkit:HoverMenuExtender ID="HoverMenuExtender1" runat="server" PopupControlID="popupImage" TargetControlID="thumbnailImage" OffsetX="-10" OffsetY="-310" PopupPosition="Left" PopDelay="100" HoverDelay="50"><br></ajaxToolkit:HoverMenuExtender>

If I use this ToolkitScriptManager instead, my HoverMenuExtender control works, but none of the RadControls render correctly.   

<ajaxToolkit:ToolkitScriptManager EnablePartialRendering="true" runat="Server" ID="RadScriptManager1">
        <Scripts>
           <%--Needed for JavaScript IntelliSense in VS2010--%>
           <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.Core.js" />
           <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQuery.js" />
           <asp:ScriptReference Assembly="Telerik.Web.UI" Name="Telerik.Web.UI.Common.jQueryInclude.js" />
        </Scripts>
    </ajaxToolkit:ToolkitScriptManager>

Any thoughts?

thanks.
