The Dink Network

I'm not entirely certain what causes it. Most of the time everything is given the curved corners, but on rare occasions I've seen squared off boxes. I think it has something to do with failiure to render the corners or something minor like that related to your screen's resolution and browser's zoomed-in/out state.
e.g Hold down the Control key and use the mouse scroll feature, just one turn should show you what I mean. I keep my browser showing everything on the DN to one-point zoomed out from default, makes things a tad smaller and less scrunched up.
