i have two windows in my code.
from child window, using window.opener, i am trying to populate the select list of parent window.
i am able to vacant the select list of parent window from child window, but not able to add anything in it.
This is working FINE in NETSCAPE, but gives error in IE4/IE5.
the error is: "server threw an exception"

The code is:

window.opener.document.forms[0].selectList.options[0] = new Option('Test', '0');
