preload a whole site with window.onload problem

[billkirim]

i am using this code to preload my site:

<script type="text/javascript">
 
document.write('<div id="loading"><br><br>The musicase is Loading...</div>');
window.onload=function(){
 
    document.getElementById("loading").style.display="none";
    document.getElementById("central").style.display="block";
}
</script>
 

in the central div is my whole site
and in the loading div is a wait message..
that seems to work on ie but not in mozilla..
But with a problem in ie.. the fisrt time works fine.. When i am refreshing the site i see the loading message and then i see the elements rendering..
The first time (without temporary internet files) works fine.. I see the whole site at the moment..

Any help?

The problem could be that you are using window.onload I'm not sure that refreshing the page is considered reloading the page I could be wrong though.
