    Consider the following code:
    <rad:RadScriptManager ID="RadScriptManager1" runat="server" />
    <asp:UpdatePanel runat="server" ID="UpdatePanel"><ContentTemplate>
        <rad:RadEditor runat="server" ID="Editor" />  
        <asp:Button runat="server" Text="Submit" OnClick="Submit_Click" />
        <div runat="server" ID="Output"></div>
    protected void Page_Load(object sender, EventArgs e)
        if (!IsPostBack)
            Editor.Content = "Hello World";
    protected void Submit_Click(object sender, EventArgs e)
        Output.InnerHtml = Editor.Content;

    Follow the following steps:
     1) Replace "Hello World" in the editor with "Telerik RadEditor"
     2) Press Submit

    Expected result:
    "Telerik RadEditor" should remain in the editor and also appear in the div below the submit button

    Actual results:
     Firefox 4 - As expected
     Chrome 10 - As expected
     IE 8 - As expected
     IE 9 - The editor resets to "Hello World". "Hello World" also appears in the div below the submit button

    Hi Jeff,

    Please use the current tags <telerik:...., the <rad:.... tags have been used in older versions of the controls.

    This is an issue with the browser's implementation of the MS AJAX framework. To work around it you need to set the UseSubmitBehavior property of the button to false. More information and an alternative solution is available in the following KB article:  This behavior has been reported for ff3.6, IE9 and IE8 since the time the article has been written.

    Can anyone please confirm that Rad window now supports IE9?

    Since we already have a live version of IE9, we would definelty like to use the controls in the new browser version.

    Please let me know.
