Ajax problem i Safari?

Jeg har et lille problem.
Min menu virker fint, og jeg kommer til de rigtige sider i IE og FF, men i Safari har den åbenbart nogle problemer engang imellem.
Den vil ikke vise indholdet! Den får fat i titlen, men indholdet vil den ikke vise, selvom den egentlig kører funktionen "ShowContent" helt igennem!

myajax.js:
var hashURL = "";
var flashURL = "";

if(location.href.toString().indexOf("#")!=-1){
    temp = location.href.toString().split("#");
    flashURL = temp[1];
}

function showContent(){
    var myajax=ajaxpack.ajaxobj;
    var myfiletype=ajaxpack.filetype;
    var res = null;
    var myTitle = null;

    var titleRx = /<title>([^<]*)<\/title>/i;
    var bodyRx = /<body[^>]*>([\s\S]*)<\/body>/i;


    if (myajax.readyState == 4){ //if request of file completed

        //if (myajax.status==200 || window.location.href.indexOf("http")==-1){ //if request was successful or running script locally
        if (myajax.status == 200) {
        //    alert('showContent START');

            if (myfiletype=="txt"){
                res = myajax.responseText;
               
                var myRes = res;
               
                myTitle = titleRx.exec(myRes);
                if (myTitle.length > 0) {
                    document.title = myTitle[1];
                }
   
                var myBody = res;
                myBody = bodyRx.exec(myRes);
                if (myBody.length > 0) {
                    myBody = myBody[1];

                    var tmp = document.createElement('div');
                    tmp.innerHTML = myBody;

                    var aDiv = tmp.getElementsByTagName('div');
                    for (var i = 0; i < aDiv.length; i++) {

//////EXAMPLE USAGE ////////////////////////////////////////////
/* Comment begins here

//Define call back function to process returned data
function processGetPost(){
var myajax=ajaxpack.ajaxobj
var myfiletype=ajaxpack.filetype
if (myajax.readyState == 4){ //if request of file completed
if (myajax.status==200 || window.location.href.indexOf("http")==-1){ if request was successful or running script locally
if (myfiletype=="txt")

}
}

/////1) GET Example- alert contents of any file (regular text or xml file):

ajaxpack.getAjaxRequest("example.php", "", processGetPost, "txt")
ajaxpack.getAjaxRequest("example.php", "name=George&age=27", processGetPost, "txt")
ajaxpack.getAjaxRequest("examplexml.php", "name=George&age=27", processGetPost, "xml")
ajaxpack.getAjaxRequest(ajaxpack.basedomain+"/mydir/mylist.txt", "", processGetPost, "txt")

/////2) Post Example- Post some data to a PHP script for processing, then alert posted data:

//Define function to construct the desired parameters and their values to post via Ajax
function getPostParameters(){
var namevalue=document.getElementById("namediv").innerHTML //get name value from a DIV
var agevalue=document.getElementById("myform").agefield.value //get age value from a form field
var poststr = "name=" + encodeURI(namevalue) + "&age=" + encodeURI(agevalue)
return poststr
}

var poststr=getPostParameters()

ajaxpack.postAjaxRequest("example.php", poststr, processGetPost, "txt")
ajaxpack.postAjaxRequest("examplexml.php", poststr, processGetPost, "xml")
