On firefox, the article border and the grey lines extend into the categories and recent articles. The article itself goes right to the edge of the space, leaving no space for the border anyway.
On IE, the border and lines extend right off the page on the right. The radio buttons have a white background.
My screen is 1280x1024.
The article text is a serif font in Firefox and sans serif in IE.
I like the new comments.
In fact, on the Romero working on MMO page, the text slightly overlaps the categories in IE.
