	// <img src="st_next.gif" oversrc="st_next_over.gif">
	// IMPORTANT: window.onload (which is used here) and BODY onload="..." are equivalent. In most browsers

	// you should ONLY use window.onload and NOT use BODY onload="...". This script will take care of running
	// your window.onload function as well the one used here.
	// NB: Quote from web forum - When you call a function with window.onload, you don't use the parentheses, 
	//		 so that the script runs the function, instead of assigining it.
	// e.g.
	// <script>window.onload = function() { myFunction('myParam'); myOtherFunction(); };</script>
	//   or
	// <script>
	//	window.onload = myFunction; // Note: no () therefore no params.
	//  // Note: myFunction MUST be in the same <script> block.
	//	function myFunction() {
  //		alert("doing myFunction");

	// <script>
	//	window.onload = new Function("myFunction('x', 'y', 'z');");
