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.
