** Title: Pop-Up JavaScript Library               **
** Date: August 23, 2000                          **
** Author:  Kofi Garbrah                          **
** Purpose: Causes a new window to be opened      **
**          containing an html document. This new **
**          window will NOT contain the toolbars  **
**          or navigation bars of an internet     **
**          browser but it CAN be scrolled or     **
**          resized.                              **
**                                                **
