  --------------------------------------------------------------------
  2001-05-04    SVJ     Created this file, added reload to openUrl()
  2001-05-08    RN      Edited openUrl(), replaced reload with assign
  2001-06-06   	GS      Edited openUrl() & reloadFrame(), replaced top with parent
  2002-05-26    CA      Edited openUrl() & reloadFrame(), it now searches for the correct frame
                        from the top and down, using the findFrame() function, it will also return
                        true/false if it found the frame or not (if opened/reloaded the frame)
  2002-05-26    CA      Removed the confirmDelete() function.
