WFM using 2001102603 Win2k on an Athlon 1400 with 512 MB.

Einar, what CPU and how much RAM do you have?

Confirmed on WinXP 2001101914 (~NS6.2), P2-266, 256MB RAM.

Mozilla loads DAGBLADET.NO in 32 seconds,
all Mozilla windows stop responding until page finishes loading.
IE loads same page in 15 seconds, Opera in 12 seconds.
Remove this bit of JS, Moz loads page much faster/doesn't hang:
<script language="JavaScript">
<!--
function MM_preloadImages() { //v3.0
var d=document; if(d.images){ if(!d.MM_p) d.MM_p=new Array();
var i,j=d.MM_p.length,a=MM_preloadImages.arguments; for(i=0; i<a.length; i++)
if (a[i].indexOf("#")!=0){ d.MM_p[j]=new Image; d.MM_p[j++].src=a[i];}}
}
//-->
</script>

Loads in 13 secs here (Athlon 728 MHz, 768 MB RAM).

Marking WFM. Reporter: Please try a more recent build and reopen this bug if it
still occurs for you:
http://ftp.mozilla.org/pub/mozilla/nightly/latest/mozilla-win32-talkback.zip
(as always, be sure to delete your old Mozilla directory before installing the
new one)
