Datepicker moves when window is resized

Datepicker moves when window is resized

Hi,
Hi,
If i resize the window datepicker doesn't move, and doesn't appear
under input field anymore. Looks like position doesn't get
recalculated. The demos i see online don't have that problem but I
cannot figure out what i am missing.
I am including the following files:
<link rel="stylesheet" href="include/overcast/jquery-
ui-1.7.2.custom.css" type="text/css" media="all" />
<script src="include/jquery-1.3.2.min.js" type="text/javascript"></
script>
<script src="include/jquery-ui-1.7.2.custom.min.js" type="text/
javascript"></script>
Datepicker initialization:
$(function() {
    $('#startDate').datepicker({
        changeMonth: true,
        changeYear: true,
        showOn: 'button',
        buttonImage: 'images/calendar.gif',
        buttonText: 'Select date',
        buttonImageOnly: true,
        dateFormat: 'yy-mm-dd',
        minDate: new Date(1997, 1 - 1, 1),
        maxDate: new Date(),
        yearRange: '1997:2009'
    });
}
Any idea ?
Thank you in advance!
Victoria
