Positioning in ipad VS comp.

Hi, not exactly sure where to post my question but...
I have a positioning problem displaying the FB comments plugin on the Ipad/BB/Android devices.. It is floating to right of the page... at the very bottom.
It works as expected in IE,FF, Chrome so its really puzzling me.

any ideas why its behaving this way?
