Try commenting out this statement:
self.turtle.tracer(False)
That helps on Python 2.6.4.
interesting. It seems as if the tracer property is a global one:
In [1]:t1=Turtle()
In [2]:t1.tracer()
Out[2]:1
In [3]:t1.tracer(False)
In [4]:t1.tracer()
Out[4]:0
In [5]:t2=Turtle()
In [6]:t2.tracer()
Out[6]:0
In [7]:t2.tracer(True)
In [8]:t1.tracer()
Out[8]:1
looks like I need to set the tracer manually.
however, even if the tracer is off, shouldn't it still draw the
line? when I put in the T.tracer(True) it works, but I shouldn't
need to I think.

I don't see where you've defined a Turtle class to instantiate sir.
Turtle is given in turtle.py. I should have subclassed it, but I was
being lazy. :)
thanks for the fast replies!

2009. The following script draws 5 circles, which it is supposed
to, but
then doesn't draw the second turtle which is supposed to simply move
forward. Any ideas?
from turtle import *
from numpy.random import randint
resetscreen()
class Circle(object):
def __init__(self,x,y,r,color):
self.x=x
self.y=y
self.r=r
self.color=color
self.turtle=Turtle(visible=False)
self.turtle.tracer(False)
self.draw()
def draw(self):
self.turtle.penup()
self.turtle.setposition(self.x,self.y)
self.turtle.setheading(0)
self.turtle.backward(self.r)
self.turtle.pendown()
self.turtle.fill(True)
self.turtle.pencolor("black")
self.turtle.fillcolor(self.color)
self.turtle.circle(self.r)
self.turtle.fill(False)
self.turtle.penup()
for i in range(5):
c=Circle(randint(-350,350),randint(-250,250),10,"red")
T=Turtle()
T.forward(100)
T.forward(100)
thanks,
