    Microturtle: I can't erase the pen trail



      I need help.

      Context: On button A pressed, I drew a square using the microturtle extension of pen-down.  Then on button B pressed, I drew rectangle again using pen-down.

      On button A+B pressed, I clear screen

      However, I realised that even when I pressed A+B, and then I press say A, the previous pattern of rectangle appears again while the LED drew the square.


      Question: how do I permanently erase the pen trail so that I see only rectangle when I press B / see only square when I press A?
