Unwanted random generation of scripted Shapes in GASP

[diemildefreude]

Hello,

I'm currently learning Python 2.7 with the help of this tutorial: http://openbookproject.net/thinkcs/pytho.../ch04.html If you look at the bottom of that page, in exercise 10, I am to produce the pictured six houses with a script. I've written a script, but when I load it, not all of the windows and doors are visible. The really odd thing is that the windows and doors that ARE visible are different every time I load the script.

Note that I'm using Windows 8, which means I'm not using the latest version of GASP, as described here: http://dev.laptop.org/pub/gasp/downloads/

Below are an image of the script and the problem. Thanks in advance.

Edit: I suspect the problem has to do with the blue boxes covering the other shapes, as everything is visible when I set the blue boxes to filled=False.

Please post the code using the Python button (6th button from the right), not a 'picture' of the code.

from gasp import *

def draw_house(x, y):


    Box((x, y), 100, 100, True, color.BLUE)     #house
    Box((x + 35, y), 30, 50, True, color.GREEN)       #door
    Box((x + 20, y + 60), 20, 20, True, color.YELLOW)       #left window
    Box((x + 60, y + 60), 20, 20, True, color.YELLOW)       #right window
    Polygon(((x, y + 100),(x + 50, y + 140),(x + 100, y + 100)),True, color.RED)

begin_graphics(title="Houses at Night", background=color.BLACK)
draw_house(20, 20)
draw_house(270, 20)
draw_house(520, 20)
draw_house(145, 170)
draw_house(395, 170)
draw_house(270, 320)
update_when('key_pressed')  #keep canvas open until key pressed
end_graphics()              #close canvas

To be honest i think you shall skip this part of the book,
because i really do not like when when author of books make wrapper around stuff like(Pygame,Tkinter...).
The you wonder about stuff like,is it the GASP tool(Pygame wrapper) that make this error?
Do they keep GASP updated,no it's from 2010 ect.
