Scrollbar, something we all need to learn to just live with, the only thing you can do to change that is add enough content to all pages to make it show on every page.

If you set the min-height of the body to something greater than the height of your browser window, then the scroll bar will always appear, but you'll have a lot of empty space on the page. Personally, I think that looks better than having a big white space under the footer.
