Scrolling External.php in iframe

Hi,

I have done a scrolling iframe in a website and the scrolling works on the Desktop, Mobile [ Portrait & Landscape ] and also works in Apple Ipad [Portrait] BUT it does not work in “LANDSCAPE”.

[Scrolling External.html in iframe is NOT working in Ipad Landscape.]

Can any please help me out with a code to set this right.

THanks
Gary
