Has anyone run into this before? Its getting into the is statement, but after that it doesn't execute the page. Works fine in FF and IE8.

    function openQuickWindow(linkHref){
      
      var url = "writeFile.cfm?writeUrl=" + linkHref;
      
    	if (window.XMLHttpRequest) {
    		xhr = new XMLHttpRequest();
    	}
    	else {
    		if (window.ActiveXObject) {
    			try {
    				xhr = new ActiveXObject("Microsoft.XMLHTTP");
    			}
    			catch (e) { }
    		}
    	}
    
    
    	if (xhr) {
    		alert("its here");
    		xhr.open("GET", url, true);
    		xhr.send(null);
    	}
    	else {
    		alert("Error");
    	}
    	return false;

      //window.open("writeFile.cfm?writeUrl=" + linkHref)
    }

Well it looks like using MSXML2.XMLHTTP.3.0 instead of Microsoft.XMLHTTP makes it work in all IE's.
