Make both instances of 'itemID' a unique label for that draggable item,
and adjust 'top', 'left', 'width', and 'height' values appropriately.
Navigator 4.x requires that these DIVs not be nested in other positioned
DIV or LAYER elements.

Remove indicated line in dragf() to keep dragged element from moving to front.
