Hi all,

I've just started to play with Microsoft WPF Ribbon libraray (October 2010, 3.5.41019.1) which downloaded from http://www.microsoft.com/en-us/download/details.aspx?id=11877[^]

After install, it puts itself into VS 2012 toolbox. Then I create the app.

The source of XAML is:

<r:RibbonWindow xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" xmlns:r="http://schemas.microsoft.com/winfx/2006/xaml/presentation/ribbon" x:Class="WpfApplication1.MainWindow" Title="MainWindow" Height="480" Width="640">
    <DockPanel>
        <r:Ribbon DockPanel.Dock="Top" Title="Title...">
            <r:Ribbon.ApplicationMenu>
                <r:RibbonApplicationMenu>
                    <r:RibbonApplicationMenuItem />
                </r:RibbonApplicationMenu>
            </r:Ribbon.ApplicationMenu>
        </r:Ribbon>
    </DockPanel>
</r:RibbonWindow>

But as seen in the screenshot (http://imageshack.us/photo/my-images/29/25761938.png/[^]), window is not look like as in the examples; no menu near window icon. Ex: http://uxpassion.com/wp-content/uploads/2008/11/06_simple_ribbon_interface-625x468.png[^] But examples said, after putting ribbon only, I must see similiar window.

When I downloaded previous version (3.5.31016.1) everything is ok.

Is there a difference between two versions? Or, am I missing something?
