On my home page the user uses the far right scroll bar to see all content towards the bottom of the page. On subsequent pages though the visible content looks almost like it is in an iframe-like window. Users have to use an inner scroll bar to see the content. How can I expand this back out to full view? Am copying & pasting some html so I am thinking I may be getting some unintended CSS maybe?

Homepage - correct

Subsequent pages - iframe-like. 

*Notice that very little vertical space is displayed
