Uploading a file when ExplorerMode is set to FileTree causes a JavaScript error in FileExplorer when the AsyncUpload is enabled.

FIX: Menu popup containers do not have background / border in metro skin

The grid adds the correct Aria-Selected attribute, but JAWS does not work

When user clicks on e.g., bold text, comment, link, etc. the UI of RadEditor is not updated

Possible workaround is using the Window's Show event to attach a handler, that re-attaches the mouseup event of RadEditor with setTimeout:

<telerik:RadWindowManager runat="server" ID="RadWindowManager1">
    <Windows>
        <telerik:RadWindow runat="server" ID="RadWindow1" VisibleOnPageLoad="true" Width="800px" Height="500px" OnClientShow="OnClientShow">
            <ContentTemplate>
                <telerik:RadEditor ID="theEditor" runat="server" Width="100%" Height="100%" EnableComments="true">
                    <TrackChangesSettings Author="RadEditorUser" UserCssId="reU1"></TrackChangesSettings>
                    <Content>
                        <h2 class="titleText">RadEditor for ASP.NET AJAX</h2>
                        <p style="text-align: justify;"><span style="font-size: 19px; color: #4f6128;"><strong>RadEditor</strong></span>
                        is not simply an <strong>
                        <span class="reComment reU1" author="RadEditorUser" comment="comment 1" title="RadEditorUser: comment 1: 6/12/2015, 11:27:35 AM" timestamp="1434097655291">HTML</span></strong>
                        Editor.
                        <a href="http://www.telerik.com/products/aspnet-ajax/sharepoint.aspx">Link</a>.</p>
                    </Content>
                </telerik:RadEditor>
            </ContentTemplate>
        </telerik:RadWindow>
    </Windows>
</telerik:RadWindowManager>

<script type="text/javascript">
    function OnClientShow(sender, args) {
        var editor = $find("<%= theEditor.ClientID %>");

        window.setTimeout(function () {
            editor.attachInternalHandler("mouseup", function () {
                editor.raiseEvent("selectionChange");
            });
        }, 0);
                
    }
</script>
