Container problems?

[ModernRevolutions]

Okay, so on my main index page you can see that none of my post is cut off on the right side. However when you click on the comments link to comment on it, for some reason the edge of the post is cut off. I did change my container code to have

overflow:hidden;

because with overflow on auto it created a scroll bar that you could scroll right with in the content box for some reason, anyone know why this is happening?

Here is my index page

I'm not picking up any problems in IE8 or FF3. Which browser version are you using. Try another browser.
