title: MFC Menu Item not properly invoking a modal dialog
body: <p>I've created a simple Dialog box with a few controls (edit, text, etc) and saved
  it to the resource folder in GME/GME.rc/Dialog</p>
  
  <p>I added an auto-gen'd event handler which created a new class (Class.cpp
  for the purposes of this example)   Note: the Class::Class(CWnd *pParent) :
  CDialogEx(Class::IDD, pParent) constructor is empty, I'm not sure if that's
  relevant but I don't think it is..</p>
  
  <p>There's a MESSAGE_MAP COMMAND(menu_item_id, &amp;class::member_function())
  invocation within the Class.cpp was auto-generated. It's wrapped in the
  standard BEGIN_MESSAGE_MAP macro stuff.</p>
  
  <p>However: when the menu item is clicked, the item remains gray. The
  properties for "enabled=true" and "gray=false" are both properly
  configured. So, I assume this is error is due to  the message handler isnt
  registered.</p>
  
  <p>Any help would be appreciated.</p>
