instead of trying to make it follow fExpando just make it a fixed
size on creation. It is invisible and extends to the bottom of the
screen. fExpando grows inside it, and the window follows fExpando.
When the window grows taller than the screenframe the arrows are
added. You can scroll with the mouse wheel, but I haven't yet gotten
scrolling to work from clicking. Deskbar still crashes when going
from Mini mode to vertical expando mode. I have no idea why.
