ho provato in questo modo la scroll è del colore dello sfondo e nn si vede
codice:
<html>
<head>
<title>Popup</title>

<script language="JavaScript" type="text/JavaScript">
function apriPOPUP(nome,titolo,larg,alt) {
      window.open(nome,titolo,'width=' + larg + ',height=' + alt);
}
</script>

<meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">

<style type="text/css">
<!--

	scrollbar-face-color: #414141;
