DatePicker and showCurrentAtPos

DatePicker and showCurrentAtPos


hello
i'm using the datepicker in a div to view the current month and the
past month
so i write:
$("#datepicker").datepicker({
     numberOfMonths: 2,
     showCurrentAtPos: 1,
     changeMonth: true
     });
.........
<div id="datepicker"></div>
but i have a problem, the position of the current month is not what i
need.
e.g.
today is 08/14/2009 so i need to see on the left July and on the
right August
what i see is on the left June and on the right July.
anyone else have this problem? is there a way to solve this isue?
thanks
