hi, i have the same problem as you, but i don't understand how do you fix it.
This works fine with firefox, but not in IE that is where has to work (political bussiness

I post here my problem...

/function that opens the new window
function openFaqList() {
for (i=0; i<document.sendFaq.isbooked.length;i++) {
if (document.sendFaq.isbooked[i].checked && document.sendFaq.isbooked[i].value=='yes')
WindowObjectReference = window.open("faqList.asp?booked=1","FAQ","width=420,height=230,resizable,scrollbars=yes,status=0");
if (document.sendFaq.isbooked[i].checked && document.sendFaq.isbooked[i].value=='no')
WindowObjectReference = window.open("faqList.asp?booked=0","FAQ","width=420,height=230,resizable,scrollbars=yes,status=0");
}
}

... html code ...
--> here the function is called
<a href="javascript:openFaqList()" class="faq-link-2">[Select]</a>
... html code ...


==> code for the new window opened
(javascript section)
var listaFAQs="";
var i;
for (i=0;i<document.selectFAQ.elements.length;i++)
if (document.selectFAQ.elements[i].type == 'checkbox') //comprobamos que el objeto es un checkbox
if (document.selectFAQ.elements[i].checked) // introducimos en un vector las FAQs seleccionadas
if (listaFAQs == "") {
listaFAQs=listaFAQs+document.selectFAQ.elements[i].name;
}
else {
listaFAQs=listaFAQs+","+document.selectFAQ.elements[i].name;
}
// pagina que tratara los datos
alert(listaFAQs);
opener.document.forms[0].action="customer_support.asp?vengode=popup&selectedfaqs="+listaFAQs;
opener.document.forms[0].submit();
// se cierra la ventana
window.close();

...
==> here we want to go back to the parent window with the selection done in this window
response.write("<form name=selectFAQ action='javascript:faq2send_selected();' method='post'>")
cont=1
rs.MoveFirst

while not rs.eof
response.write("<input type='checkbox' value='" & rs("faq_id") & "' name='checkbox_"& rs("faq_id") &"'>"&cont&". "&rs("title_en")&"<br>")
rs.movenext
cont=cont+1
wend
response.write("<INPUT TYPE=SUBMIT VALUE='Hecho'></form>")
...


Thanks !!!
