Probleme mit DHTML-Menü / öffnen Browserfenster mit JavaScript

So sieht das DHTML-Menü meiner Web-Seite aus:

...
<script type="text/javascript" language="JavaScript1.2">
<!--
stm_bm(["menu36fa",400,"","blank.gif",0,"","",0,0,250,0,1000,1,0,0,""],this);
stm_bp("p0",[1,4,0,0,2,2,0,0,100,"progid:DXImageTransform.Microsoft.Fade(overlap=.5,enabled=0,Duration=0.60)",-2,"",-2,50,0,0,"#fffff7","#ffff99","",3,0,0,"#000000"]);
stm_ai("p0i0",[0,"Willkommen","","",-1,-1,0,"body.html","detail","","","","",0,0,0,"","",0,0,0,0,1,"#ffff99",0,"#008000",0,"","",3,3,0,0,"#fffff7","#000000","#008000","#ffff99","10pt 'Comic Sans MS','Arial'","10pt 'Comic Sans MS','Arial'",0,0]);
stm_aix("p0i1","p0i0",[0,"Neuigkeiten","","",-1,-1,0,"java script:window.open(\"neuigkeiten.html\", null, \"scrollbars=yes,resizable=yes,width=450,height=200\");","_blank"]);
stm_aix("p0i2","p0i0",[0,"Veranstaltungen","","",-1,-1,0,"veranstaltungen.html"]);
...
stm_ep();
stm_em();
//-->
</script>...

Probleme macht dieser Teil:
stm_aix("p0i1","p0i0",[0,"Neuigkeiten","","",-1,-1,0,"java script:window.open(\"neuigkeiten.html\", null, \"scrollbars=yes,resizable=yes,width=450,height=200\");","_blank"]);

Es soll sich die Seite neuigkeiten.html als sep. Browserfenster in der Größe 450x200 öffnen. Tut es auch, aber leider öffnet sich immer noch en weiteres Browserfenster in dem nur das Wort [object] steht.

Was muss ich ändern?

Hilfe!
