Summary: turtle.py deferres exec of stmnts with tracer(0)

Initial Comment:
interactive use of turtle.py becomes impossible,

e.g.when issuing tracer(0) because in this

case apparently updating of Canvas-Widget is

deferred ...

... until the next tracer(1)

(one can observe this when running the demo() )



Inserting a _canvas.update() call in _draw_turtle()

for the case that tracing is off seems to work:



    def _draw_turtle(self,position=[]):

        if not self._tracing:

            self._canvas.update()  # <== insert this line!

            return

        if position == []:  # etc.etc.





I have attached a corrected version as turtle_.py

You did not attach a file.  You must select a filename *and* turn on the checkbox to do so.
