Increased font size = broken forum layout: Why?

I do a lot of browsing on my sofa in front of the TV, and since the internet is not really designed for that, I just increase the font size to be able to read. It works pretty well on most websites, but unfortunately here which is where I do quite a lot of my browsing, the layout breaks horizontal scrolling.

Is this a vBulletin deficiency? Seems like basic trivial stuff that should have been there.

real men use a desk ;)

The ad code made that happen, it’s not a VB issue.

Well, what’s consistent layout when compared to knowing about TERA: Fate of Arun!
