Userdefined Page Size issue

Hi,

I am using Visual Studio 2012 with Crystal Report Developer 13. I have issue with User Defined Page size. Few of our reports are on Odd Page size like 16" Width X 12" Height and i want to design a report on it in portrait mode.

When i try to define this page size crystal designer is converting the mode to landscape. i observed while we put higher value on Width then height it does the same.
