    I am trying to use the following code from your demo to try and use the windows control:

    function openRadWin() {
            radopen("http://www.telerik.com", "RadWindow1");
        }

    <telerik:RadWindowManager ID="RadWindowManager1" runat="server" EnableShadow="true">
        <Windows>
            <telerik:RadWindow ID="RadWindow1" runat="server" ShowContentDuringLoad="false" Width="400px"
                Height="400px" Title="Telerik RadWindow" Behaviors="Default">
            </telerik:RadWindow>
        </Windows>
    </telerik:RadWindowManager>

    <button style="width: 150px; margin-bottom: 3px;" onclick="openRadWin(); return false;">open RadWindow</button>

    I get an error, screen capture attached.

    Hi Andrew,

    This error is observed when an older version (prior to Q1 2011) is used to open a RadWindow under IE9. This browser introduced a breaking change in the way iframes are handled and thus the first version of the RadControls that can work with it is Q1 2011. More information about this scenario is available in this forum thread.
