Days in previous month selectable before startDate

What steps will reproduce the problem?
I have a start-end date setup. Startdate is always today, enddate some day in 
the future.

<code snippet>
    $('.date-pick').datePicker(
    {
        clickInput: true,
        startDate: '2012-08-31',
        endDate: '2014-01-20 00:00:00'
    }
</code_snippet>

What is the expected output? What do you see instead?
I do expect to be able to choose today, but not yesterday or days earlier than 
that. Screenshot of error is attached.

Please provide a URL to a page displaying the problem.
Log on system, cannot do that.

What version of the datepicker are you using? On what operating system? And 
Which Browser?
Using dp v.2.
Client OS is Win7 Ent
Same result produced in IE9, Chrome, FF 11 and Opera 12.01.

Please provide any additional information below.
