loading <div>

[Disaster-sama]

im not sure how it works but, i was wondering how does the "loading" icon can be displayed on screen on a certain position even when you scoll down or up?
i found that gmail has that, but when i use the script the loading icon does not follow the scroll and stays in the same position. any help?

This script corrects position when scrolling window. Attach it to layer with "loading".

<script>d=document;g=function(X){return d.getElementById(X);}
d1top=200;d1left=120;
onscroll=function(){g('d1').style.top=d1top+d.body.scrollTop;g('d1').style.left=d1left+d.body.scrollLeft;}
if(self.addEventListener)addEventListener('DOMMouseScroll',function(){setTimeout(onscroll,1)},!1);
(genBr5x=function(N){while(N)d.write(N--+'<br><br><br><br><br>');}
)(20)
</script> 
<div id=d1 style="position:absolute;top:200px;left:120px;border:1px solid red">Floating div</div>
</body></html>
