bug: DatePicker & IE8

[delta77]

Hello, I have found one unpleasant bug with DataPicker and IE8 (in other browsers its Ok). So, if you initialize datepicker with month and years comboboxes $('#datepicker').datepicker({changeMonth: true, changeYear: true});

After you've changed the year and then trying to change the month, in this case month combobox immediately closed on entering!

The same problem if you have changed the month, and trying to change the year, after entering years combo its getting closed.

By another words, I can change the month only at second attempt, entering this combo :(

It looks very unpleasant. Please help to fix this bug.

Best Regards, delta77
