xp service pack 2 using javascript redirect for 1 frame in frameset

completely hangs the browser..

[ikbenhet1]

I have a frameset, and i am using this:

window.setTimeout("location.href='url.php?user=x&wachtwoord=y';",13000);
and for other pages i just use this:
location.href='url.php';

To load another url into 1 frame of a frameset.
it works just fine in all OS'es exept xp service pack 2 .

Users are telling me that their browser completly hangs after a little while (when it refreshes).
Does anybody recognize this problem? maybe even know a solution for it? thanks

i'ts fixed, just that i didn't know i could hang all of IE with xp sp2 (only way out was ctr-alt-delete) by a javascript error, i had put somthing in the head what should be in the body, lika parent.scrol loop .

This post can be deleted sorry and thanks.
