in ajax.js

xhr:function(){
	return window.ActiveXObject ? new ActiveXObject("Microsoft.XMLHTTP") : new XMLHttpRequest();
},

should be something like

xhr:function(){
	if (window.XMLHttpRequest) {
		return new XMLHttpRequest();
	}
	else if (window.ActiveXObject) {
		try {
			return new ActiveXObject("Microsoft.XMLHTTP");
		}
		catch(e) {
			try {
				return new ActiveXObject("Msxml2.XMLHTTP");
			}
			catch(e) {
				return false;
			}
		}
	}
},

The IE7 native XMLHttpRequest object was broken and is being circumvented so the code can't be implemented that way. The one thing in particular I can remember is that IE7 XHR doesn't support file urls. So the test for ActiveXObject has to be done first.

It sounds like Microsoft.XMLHTTP isn't installed on some systems but Msxml2.XMLHTTP is then? What version of Windows and service pack is this?
