Homepage Changing to Sidebar of Most Recent Post

I want to change the sidebars only on certain posts and nowhere else. Well I noticed that my homepage is changing to show the sidebar associated with the most recent post. My category, tag and other pages all keep my default sidebar. But the homepage does not.

How do I force the homepage to always show the default sidebar and not change to show the sidebar of the newest post if it differs from the default one?
