title: windows 8 Scrollbar in Scrollview by touching not visible
body: <p>In my app I have a ScrollViewer in which I present Items in a StackPanel. When I scroll it with mouse, the vertical scrollbar sit visible. When I scroll this via finger touch, the vertical Scrollbar is unvisible. Is it possible to show my vertical Scrollbar in touch mode? In the following my xaml-code:</p>
  
  <pre><code>    &lt;ScrollViewer Width="580"
                    Height="580"
                    Visibility="Visible"
                    IsDeferredScrollingEnabled="True"
                    VerticalScrollBarVisibility="Visible"
                    HorizontalScrollMode="Disabled"
                    ZoomMode="Disabled"&gt;  
              &lt;StackPanel x:Name="viewPanel"
                  Background="Transparent"
                  Orientation="Vertical"
                  Width="Auto"
                  Height="Auto"/&gt; 
  &lt;/ScrollViewer&gt;
  </code></pre>
