I have to view the browser in full screen (you can press F11 for the short-cut) to see the two remaining columns in their right position. Maybe it's just because I have a small screen on my laptop (14.1 inches wide-screen) or a lower resolution... oh there you go! I fixed my browser issues hehehe. Turns out that I just had to make the resolution higher hahaha!
It really helps when you have some know how with computers. It sure makes life easier. ^_^
