title: WPF TextBox with SpellCheck.IsEnabled="True" - No SpellChecking happening?
body: <p>I just wanted to play around with WPF SpellCheck a little, but although the Attached Property is set, there's no underlining of whatever I type.</p>
  
  <pre><code>SpellCheck.IsEnabled="True"
  </code></pre>
  
  <p>If I remember correctly, SpellCheck is supposed to add Menu Items to my ContextMenu as well, isn't it? That doesn't happen either...</p>
  
  <p>BTW, my machine is running .Net4.</p>
  
  <p>Do I have to enable this globally somewhere? All tutorials and so forth just mention setting SpellCheck.IsEnabled gets you going...</p>
