Preloader only works in player 7

Question

I have a preloader for my web site and I want it to show the
percent loaded. I could not get the percent to update, the
animation for the preloader does work. Finally I tried dropping
down from version 8 in the publish settings to version 7 and it
works fine. I tried stripping almost every thing out of the site
but I still need to drop down to version 7 for the preloader to
work. If I start from scratch and build a simple site the same as
my stripped down site the preloader will work in version 8.
Any ideas?
stop();
myInterval = setInterval(preload,100);
function preload() {
var current = _root.getBytesLoaded();
var total = _root.getBytesTotal();
var pctLoaded = Math.round(current/total*100);
pct_txt.text = pctLoaded;
if (current >= total) {
gotoAndPlay("main",1);
clearInterval(myInterval);
}

don't use the goto functions and don't use scene info in your
actionscript navigation. use the goto methods and use frame
labels.
