My emacs frames have an unwanted border, even if maximized:
The blue thing at the bottom is the border drawn by the openbox. The dark gray/black interior is Zenburn's background. But what is this light gray thing between them, and how do I disable it? It is there even if the window is maximized :(
EDIT: To clarify, I am asking not about the fringe which is only on the left side of the picture, but about the lighter grey border which is both at the bottom and at the left side. It seems to be window manager specific: I see it with openbox and xfwm, but it is absent if I use xterm session.
