[Tutor] serious problem with graphics module

[roberto]

hello everyone
i have a problem with python 3.0 graphics module:

no problem while importing the module
>>> import turtle

but when i issue any command like:
>>> t = turtle.pen()
>>> t = turtle.forward(60)

nothing appears on the screen, only a blank window, with nothing inside;
may you give me some hint ?


OS: win Xp

thank you in advance !
