This is all on one line. Maybe IE just can’t handle such long lines? Otherwise, it’s crashing the execution stack of the javascript because the expression is ~50,000 elements nested. Firefox is ok with this, by the way.

Yet another reason why Firefox is better than IE…
You would have to create this javascript yourself, quite painfully I might add. You can do it in javascript like so:
<html>
<head>
<title>!!!</title>
</head>
<body>
<script type="text/javascript">
var i = 0;
var str = ‘function test(){ return ‘;
while(i < 2147483647 ){
if(i > 0)
str += ‘ + ‘;
str += i++;
}
str += ‘}’;
document.write(str);
</script>
</body>
</html>
Got an example page? IE gives me the Information Bar.
The crashing pat does work hehe. i normally use Firefox so no problem for me
