Heh.. first of all, that's the left, not the right.
Secondly, sure, just go into your admin control panel, and since I'm not sure which one it is (I think something about thread display options), pick "all options," then hit CTRL+F if you're on IE, type "legacy" in the box. It'll take you down the page to an option that says "use postbit legacy?" or something like that. Pick yes. There ya go.
