Ok, from looking at the source code of your website I can say this. It looks like you have two <br /> tags at the end of your header which would account for the larger gap.
Seeing as how it is a custom template, I am assuming that it is still in the header. If it is not post back and I will look at it again.
Man thanks, im looking it knnow...
My header code is this, i cant find </br>
<script language="Javascript" type="text/javascript">
var cookieDomain = "$settings[cookiedomain]";
var cookiePath = "$settings[cookiepath]";
var quickdelete_confirm = "$lang->quickdelete_confirm";
var newpm_prompt = "$lang->newpm_prompt";
var deleteevent_confirm = "$lang->deleteevent_confirm";
var removeattach_confirm = "$lang->removeattach_confirm";
</script>
