menu popup desformata página

[zerebeu]

Boas

Tenho um menu popup(feito no software Ultra MEnu), em que ao fazer o rollover nos itens que têm subramos, o layout sobe uns pixeis, desformatando-o (esse comportamento só se verifica no IE).

<script type="text/javascript" language="JavaScript1.2">


BuildLayer('h','','','','10','10','','','','2','0','1px Solid #000000','1px Solid #000000','1px Solid #000000','1px Solid #000000','left','#FFFFFF','','1','1','','Filter:none(Duration=0.5)','','#C0C0C0','0','Default','Pointer','','100','0','#FFFFFF')
SwapDiv('wme1','','File','blank.gif','blank.gif','0','0','arrow.gif','arroww.gif','7','7','auto','auto','Chicago,Arial,Verdana','Chicago,Arial,Verdana','9pt','9pt','normal','normal','#000000','#FFFFFF','normal','normal','none','none','#FFFFFF','#000000','blank.gif','blank.gif','1','1','1','1','1px None #000000','1px None #000000','1px None #000000','1px None #000000','1px None #3A4057','1px None #3A4057','1px None #3A4057','1px None #3A4057','middle','left','','','','_self','','','0','blank.gif','blank.gif','auto','auto','0','0','0')
FreeLayer('wme10','','6','v','0','0','2','0','1px Solid #000000','1px Solid #000000','1px Solid #000000','1px Solid #000000','#FFFFFF','','1','1','','Filter:progid:DXImageTransform.Microsoft.Inset(,enabled=0,Duration=0.2)','','#C0C0C0','0','100')
SwapDiv('wme9','wme1','New               ',_,_,_,'16','blank.gif','blank.gif','0','0',_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,_,'0px None #FFFFFF','0px None #FFFFFF','0px None #FFFFFF','0px None #FFFFFF',_,_,_,_,_,_,_,_,_,_,_,_,'0',_,_,_,_,_,_,_)
InitDiv();
Filter('True','','')
HideDiv();


</script>







e no CSS:



body {
 font-family:Tahoma, Arial, Helvetica, sans-serif;
 font-size: 1em;
 background: #ffffff url(../imagens/fundo.gif) repeat-x;
 z-index:0;

}



#header {
 width: 810px;
 height: 157px;
 background: transparent url(../imagens/logo.gif) no-repeat;
 margin: 9px auto 0px auto;
 }

Agradecia muito qualquer ajuda, visto andar há horas e horas a bater com a cabeça
