// DESCRIPTION: This script will create scrolling messages witnin a defined   //
//              area.  The message color and style, message spacing, scroll   //
//              speed, scroller dimensions, scroll direction (horizontal or   //
//              vertical), and scroller background color can be adjusted.     //
//              Each message can be given a specific URL, target window, and  //
//              message.  Scrolling stops when a cursor is over the scroller. //
//              This script works on Netscape 6+ and IE 5+ browsers.          //
//              Unsupported browsers will not display anything.               //
//       USAGE: This script is free to use in any non-commercial application. //
