    I am using the Ajax Rad Menu from Q3 2010 in Visual Studio 2010 on Windows 2008 Enterprise Server
    This error happens in my development environment on Windows 7 and in production on Windows 2008 Server

    Put the Rad Menu into your project and configure it to look something like this:

    <telerik:RadMenu ID="RadMenu1" Skin="Windows7" EnableEmbeddedSkins="False" OnClientItemClicking="myClickFunction" runat="server">
        <ExpandAnimation Type="InOutQuad"></ExpandAnimation


    Add your own Menus and sub menus as you see fit.  Run the application out of VS2010.  Notice that when you run the page you created and pass the mouse over the menus the menus drop down and slide out normally.

    In the browser (IE8) go to the Tools | Internet Options menu.  When the Internet Options dialog box comes up, click the Security tab.  Select the Trusted Sites zone and click the Sites button.  Uncheck the "Require server verification" check box and add the http://localhost to the Websites list.  Click Close then click OK on the Internet Options diaolog box.

    Pass your mouse back over the menus and you should get a javascript error that shows in VS2010.  In the Telerik.Web.UI.WebResource_2.axd?... file you get this error in this function: " 'type' is null or not an object "


    Sys.UI.DomEvent=function(e){var a=e,b=this.tyle=a.type.toLowerCase();this.rawEvent=a;this.altKey=a.altKey;

    where    b=this.tyle=a.type.toLowerCase()   is hghlighted in yellow showing the statement that failed

    Go ahead and click the Continue button on the error dialog until the error clears and passes execution on to the browser.  Now refresh your browser by hitting F5.  Pass your mouse over the menus and the error no longer happens.

    Can anyone tell me why this might be happening?

    Hi Ralph,

    I've just answered another ticket regarding the same problem.
    Could you please try to test the same scenario with a standard asp:menu and with/without asp:ScriptManager?
    I believe it is something specific to the asp:ScriptManager, because the problem disappears when it is removed from the page.

    I'm seeing this behavior as well. Is there a resolution?
