Try this:

  let optional :: <lpvariant> = make(<lpvariant>);
  IWebBrowser2/Navigate($0, 
                        "www.yahoo.com", 
                        optional, 
                        optional, 
                        optional, 
                        optional);    


This is what I use in my web browser example:
