Apparently IE Windows only recognizes the multiple attribute
onFocus(), which, as far as I'm concerned, is a bug. The solution is
therefore to place the focus on the select box automatically:

form.appendChild(select);
select.focus();

After that you might put the focus on the first, normal, select.
