You might be trying to write to a section that is currently off
screen. Seems to me when I was doing some curses stuff that when I
tried to write to one more row than could be fit onto my terminal that
error would come up.

Try doing the following code and make sure that you can enough space to draw it.

>>> (height, width) = screen.getmaxyx()
