As you surmise, it's probably something to do with the fact that you're
creating the option element in one window and trying to add it to the
document in another - this is not allowed under the DOM standard.

Try:

var newOptionText = window.opener.document.createTextNode("Your text");
var newOption = window.opener.document.createElement("option");
newOption.appendChild(newOptionText);
newOption.setAttribute("value", Your value");
window.opener.document.form1.mylist.appendChild(newOption);

which uses the opener window's document to create the text node, and
should therefore be OK. It's also going to work cross-browser (IE,
Mozilla Firefox, Opera and any other browser that supports the DOM),
whereas I think I'm correct in saying that new Option() is a
non-standard Internet-Explorer-only technique.

(BTW, I haven't tested the above code, but barring typing mistakes, it
should work :-)

HTH,

Nick.
