Using the chameleon test template: boundingboxpopupwidget000.html 

The follow error has occured.

  Fatal error: Cannot instantiate non-existent class: mapnavigator in
C:\ms4w\apps\chameleon\htdocs\widgets\BoundingBoxPopup.widget.php on line 95
  
  i) I am assuming that the reason for this error is that this widget needs the
navigation widgets like zoom in. 
  I thought that this widget would work if the mapDHTML widget was present, but
it does not. When loading the template with both the Bounding Boxpopup  widget
and MapDHTML widget there is no change in the display. Not even the a map was
displayed, only the above error.
  
  ii) This widget should be able to load independently from all widgets, from
the popup display the only thing it requires is the extent of the mapfile. Since
this is given, this button should be present and that when the button is
selected the popup should contain the full extent of the none map area. Also a
if no mapdhtml widget is present a WARNING should be present to say at least the
requests cannot be processed from the popup.
  
  iii) Should this widget have the ability to have the popup window as an
embeded feature. I see no parameter found in the documentation.
