[jQuery] problem with jQuery().TransferTo complete:

Hi,
I am having a problem with jQuery().TransferTo complete:
The complete is only called the first time the method openWindow is
invoked, why?
This is the method invocation sequence
openWindow -> Success
closeWindow -> Success
openWindow -> alert "inside if, opening window..." Success
     complete: never gets invoked
Thanks for any help!!
    function openWindow(messageText) {
        if($('#window').css('display') == 'none') {
            alert("inside if, opening window...");
            $("#appendRow").TransferTo(
                {
                    to:'window',
                    className:'transferer2',
                    duration: 400,
                    complete: function()
                    {
                        alert("complete..");
                        jQuery('#window').show();
                    }
                }
            );
        }
        $('#window').blur();
        return false;
    }
    function closeWindow(){
        $('#window').TransferTo(
            {
                to:'appendRow',
                className:'transferer2',
                duration: 400
            }
        ).hide();
    }
