Side bar on front page has mind of it own.

This is happening with every theme I download. On my front page, the sidebar, which should be in the right column, gets knocked down to the bottom of the page, below the body of posts. If I click through to a single post, it’s back justified to where it should be – the right side bar.

Again, it’s happened on every theme. Don’t know what to do. Thanks.
