wrong comment page AFTER posting

Hi
I used the popup-comment page for comments. But here’s the thing: When someone posts a comment inside the popup, it refreshes the wrong page. I would like it to refresh to for example: wp_comments_popup.php?p=2&c=1
instead of what it does now: index.php?p=2
does anyone know how to fix this?
i’ve been looking at the wp_comments_post.php page and found this:
$location = get_permalink($comment_post_ID);
if ($is_IIS) {
header(“Refresh: 0;url=$location”);
} else {
header(“Location: $location”);
}
i thinks it is to be done here somewere, but before i do something terribly wrong i thought i’d ask 😉
thanks,
amoen
