Most likely, you had been referencing tw, the TurtleWindow instance from lc, the LogoCode instance, e.g., lc.tw. Now you can reference tw directly, e.g., tw. To reference lc, use tw.lc. Under most circumstances, Turtle Art will detect when myblock is looking for lc rather than tw and it will pass the correct argument. 106 ENHANCEMENTS * Added sharing to draw_text, fill_polygon,
