title: Why does my WPF application crash when I bump my mousewheel?
body: <p>When I bump my mousewheel, my WPF application crashes sometimes, with an OverflowException. Here's the start of the stack trace: </p>
  
  <pre><code>at System.Windows.Shell.WindowChromeWorker._HandleNCHitTest(WM uMsg, IntPtr wParam, IntPtr lParam, Boolean&amp; handled)
  </code></pre>
  
  <p>From that, I've traced it down to the WindowChrome - I can even reproduce it with just the WindowChrome. But it seems like it has to be fullscreen. What's going on here? Is there a workaround?</p>
