title: WPF MouseLeftButtonUp Not Firing
body: <p>When I use the <code>MouseUp</code> event, I can get it to fire with a mouse right-click. But <code>MouseLeftButtonUp</code> won't fire with either click!</p>
  
  <pre class="lang-xml prettyprint-override"><code>&lt;Button MouseLeftButtonUp="btnNewConfig_MouseUp"  Name="btnNewConfig"&gt;
      &lt;StackPanel Orientation="Horizontal"&gt;
          &lt;Image Source="Icons\new.ico" Height="24" Width="24" Margin="5"/&gt;
          &lt;TextBlock VerticalAlignment="Center"&gt;New&lt;/TextBlock&gt;
      &lt;/StackPanel&gt;
  &lt;/Button&gt;
  </code></pre>
  
  <p>I know this is most likely something simple. Thanks for the help!</p>
