Slackware :: Black / Dead Space In Terminal (Tiling Window Managers)

I've been playing around with two tiling window managers, scrotwm, and xmonad. I like xmonad better, but that's not the point. The point is that they both produce these strange black bars at the bottom when a terminal window is opened. Note that this does not happen in fluxbox/openbox, my other wm.
Its hard to explain, so please see the screenshots: [URL]
Note the black bar, or just dead at space the bottom of the the terminal windows. In the third image, the prompt is at the "bottom" of the window, or what should be. Again, this only happens in scrotwm and xmondad, no other wm's I've tested.
