title: wxWidgets can't receive Right mouse click
body: <p>I'm trying to add a context menu to a grid control in wxWidgets 2.9.4 on Windows 10, and while I can get the context menu key to work right clicking doesn't.  Right now I have the following in the header</p>
  
  <pre><code>void handle_contextMenu(wxContextMenuEvent&amp; event);
  void handle_rightButton(wxMouseEvent&amp; event);
  </code></pre>
  
  <p>and in the constructor</p>
  
  <pre><code>Bind(wxEVT_CONTEXT_MENU, &amp;DataGrid::handle_contextMenu, this);
  Bind(wxEVT_RIGHT_UP, &amp;DataGrid::handle_rightButton, this);
  </code></pre>
  
  <p>neither work for the right mouse button.</p>
