Now I'm doing this:

def clrscr():
    global stdscr
    (maxy,maxx) = stdscr.getmaxyx()
    line = ' ' * (maxx-1)
    for row in range(maxy):
        stdscr.addstr(row, 0, line, curses.color_pair(1) )

which works fine except that the right side of the screen is still black.
It is a very clumsy solution. Any ideas?
