No reseize scroll menu

<form action="http://localhost/send.php" method="post" target='iwin' name="form" onsubmit="return window.open('', 'iwin', 'height=300, width=400, status=no,toolbar=no,location=no,menu=no,resizeable=no,scrollbars=no'), setTimeout('document.form.reset()',200);return true;">
besked:<br>
<input type="text" name="besked" size="30" maxlength="100"><br>
<input type="submit" name="skriv" value="Gem">
</form>

Den sletter også selv det indtastede data i formen, når man trykker Gem

<form action="http://localhost/send.php" method="post" target='iwin' name="form" onsubmit="return window.open('', 'iwin', 'height=300, width=400, status=no,toolbar=no,location=no,menu=no,resizeable=no,scrollbars=no')">

Så det er denne kode du leder efter.
