Overflow bringing me down

Hi,

On a particular DIV, I have the overflow property set to auto. When
the DIV suddenly gets a lot of data in it, a scroll bar appears.
Problem is, when I scroll down as far as I can on my browser, I still
can't see the bottom of the page:

Anyone have ideas on properties I might be able to set or things I can
do to overcome this?

Thanks, - Dave
