    Hello, I am using the latest RADControls.  I have created a simple page as shown below with a RadScriptManager and a RadMenu.  After this page loads there are about 15 items in the menu.  When the user hovers over one of the main menu  items and the sub-menu (contining about 5 of those items) pops up the CPU jump to near 100%.  If the user then moves the mouse away and then back the CPU consistently remains extremely high.  The application is running in debug=false mode and the ViewState for the menu is disabled.  Those were the only two perfomrance tips that I have been able to find.

    <telerik:RadScriptManager ID="RadScriptManager1" runat="server">
            <asp:ObjectDataSource ID="dsNavMenu" runat="server" OldValuesParameterFormatString="original_{0}"
                SelectMethod="Get" TypeName="NavMenu_BLL">
                    <MyUser:CurrentUserParameter Name="UserName" />
                <telerik:RadMenu runat="server" ID="mNav" DataFieldParentID="ParentId" DataSourceID="dsNavMenu"
                    DataTextField="Link" DataFieldID="Id" DataNavigateUrlField="NavigateUrl" Skin="Default"
                    CssClass="Menu" EnableViewState="false">

    Hello Alex,

    I tested the issue that you describe using our on-line demos but I could not reproduce it. See the attached video here. Can you please send us either a live url ot simplified runnable project that we can test locally and inspect where the issue comes from?
