innerHTML problem (Javascript AJAX IE 8)

[Abid]

I have been stuck on this for 2 days, my code works fine in Firefox and IE7 but in IE 8 it just crashes the browser.

The function is called via an onkeyup event on a text box. The URL brings back HTML which is passed into a DIV element called "branchresults". I have a feeling its something to do with innerHTML.

function getBranches() {
    
        var clientID = document.getElementById("dropClients").value;
        var branchNum = document.getElementById("txtBranchNum").value;
        if(clientID==""){
            alert("Please select a Client ");    
            return false
            
        }

        var strURL="ajaxgetbranches.php?client="+clientID+"&branch="+branchNum;
        var req = getXMLHTTP();
        
        if (req) {
            
            req.onreadystatechange = function() { 
                if (req.readyState == 4) {
                    
                    if (req.status == 200) {
                            
                        rtnHTML=req.responseText;
                        //branchresults is a div element
                              document.getElementById("branchresults").innerHTML = rtnHTML;
                                        
                    } else {
                        alert("There was a problem while using XMLHTTP:\n" + req.statusText);
                    }
                    req.open("GET", strURL, true);
                    req.send(null);

                }                
            }            
            req.open("GET", strURL, true);
            req.send(null);
        }        
    }

I have fixed the problem how silly of me I had this line in twice:

req.open("GET", strURL, true);
req.send(null);

I am just seraching around for 2 days about the innerHTML issue in IE. and found out that the HTML content assigned to innerHTML property having the problem.As html the content containg table layout causing the problem.

I replaced table layout with div layout and it is working fine on IE.
