Here is my current environment: macOS: 10.12.4 Wing 101 version: 6.0.4-1, which uses Tcl/Tk version 8.5.?? Python and IDLE version: 3.6.1, which uses Tcl/Tk version 8.5.18 Every time I run code in Wing 101 that uses Turtle graphics, it does run in the Turtle window, but I cannot close the window. If I click the red (close window) button, the beachball spins endlessly. I had to 'force quit' it. If I run the same code in IDLE, the code runs flawlessly and I can close the window after graphics are rendered. 1. It is annoying to 'force quit' the window every time. Why it is happening in Wing 101? 2. How can I tell Wing 101 to use the latest version of Tcl/Tk, 8.6.4, which I have installed?
