[Planner] howto change the project starting date

[cheng chung yan <yan amonics com>]

hi
i open the Project properties dialog. In General tab, it has a "Start" 
field, i try to type-in a day, then click "Close" button, no any changing.

I don't know it is a bug or i typed-in a wrong date format. In the old 
version of mrproject, it will shows a calender and just click to choose, 
it works. Why that change to type-in date by unknown format?

Could you please point me how to do for changing project starting date?

thanks
yan
