Scrolling the whole page when only the center panel overflows in border layout?

Hi,

I am using ExtJs 4.2.1 with SA 3.1. I understand that viewport does not provide scrolling, but is there any way/hack to have a scrollbar on the whole webpage instead of center panel when the Center panel overflows in the border layout. I have north, west and center regions in the border layout. Basically, the North region contains the App logo, Center region will be a card layout with most views being form panels. Few long forms overflows the center container and then the scrollbar appears from middle of the page (after the north region ends), and it looks like they aren't part of same webpage.

Is there any solution?

Regards,

Saurav
