	//alert(navigator.userAgent);

	// We can normally distinguish a true IE from, say, Opera masquerading as IE
	// from the presence of "MSIE" _and_ absence of "Opera" (or whatever other browser name)
	// in the userAgent string.  However some browsers, such as Konqueror, will give up all
	// traces of their own identity when implementing the "hack" to identify themselves as
	// IE.  However, since that is not the default behaviour, I feel the following is
	// sufficient for distinguishing within the class of recent DOM-enabled browsers:
	//
	//if(navigator.userAgent.indexOf("MSIE")){
	var agent=navigator.userAgent;
	if(agent.indexOf("MSIE")>0){
		//
		// Check against other browsers masquerading as IE:
		//
		if(agent.indexOf("Opera")>0) return;
		if(agent.indexOf("Gecko")>0) return;
		if(agent.indexOf("Konqueror")>0) return;
		if(agent.indexOf("KHTML")>0) return;
		if(agent.indexOf("Safari")>0) return;
		
		//
		// Warn the user about the problems with viewing in IE:
		//
		if(showWarning){
			warningNode=document.getElementById("IEWarning");
			warningText  = '<p><span class="warning">Warning:</span> ';
			warningText += 'Ender\'s web pages adhere to <a href="http://www.w3c.org">W3C</a> ';
