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 Gregor Lingl
