Blog using Ajax

I’ve used this awesome plugin a lot. I think it does the trick but I’m running into a problem. When you go to the blog, it does work. But when you click “older entries” it doesn’t.

Now when I refresh the browser, it goes back to main blog section. I think it may have to refresh to put that previous section to equal heights. Any thoughts on this?
