I just setup the ros environment, trying to walk through the tutorials.  I
get to running turtlesim, but the turtle is not visible anywhere in the
blue window.  any help would be great.  here is the output I get:

wes@wes-G73Jh:~/ros_workspace$ rosrun turtlesim turtlesim_node
[ INFO] [1335882178.594059636]: Starting turtlesim with node name /turtlesim
[ INFO] [1335882178.605867456]: Spawning turtle [turtle1] at x=[inf],
y=[inf], theta=[0.000000]

thanks
