//      This function uses a technique similar to that described in KB
//      article Q109175 to locate the previous instance of the application.
//      However, instead of searching for a matching class name, it searches
//      for a matching caption.  This allows us to use the normal dialog
//      class for our main window.  It assumes that the AFX_IDS_APP_TITLE
//      string resource matches the caption specified in the dialog template.
