Unsemantic grid issues

Hi,

First, sorry for the duplicate topic. I was having trouble giving access to the server, but that seems to be fixed with the new site address listed below. Anyhow, onto the issue:

I’m having trouble with getting the unsemantic grid working properly. If you visit my url from a desktop, you will see a “HOT” box 4 column grid at the top of the content. As you resize the browser window smaller, you notice the grid breaks at some point in tablet mode, before it fixes itself once it gets even smaller.

Is this a bug?

Thanks.
