jQuery DatePicker - window closes after selecting month or year

jQuery DatePicker - window closes after selecting month or year

Hello,

I'm using jQuery DatePicker with the following date picker options:

datepickerOptions: {
                        changeMonth: true,
                        changeYear: true,
                        yearRange: '-15:+15'
                    },

When I pop up the calendar, I correctly see drop-downs for month and year.  However, when I change the month or year, the calendar closes.  I then have to click on my input field to pop it up again, so I can actually pick a date for the selected month/year.

How do I stop the calendar from closing every time I select a month or year?  

Platform: Firefox 20.0 on a mac

Thanks.
