In chapter 7 "colors and styles" section of the book, there are some exercises that seem to freeze the kernel when I click "check answer". For example, exercise 2.4 says
"Make a list of colors with hues varying from 0 to 1 in steps of 0.02."
When I put the correct answer Table[Hue[x], {x, 0, 1, 0.02}]
, I can evaluate and it compare to the "expected output" and it matches and works fine. However, if I click "Check my solution", it will run indefinitely and prevent me from evaluating anything else until I restart Mathematica.
Even clicking "abort evaluation" in the menu or "remove from evaluation queue" does nothing, only a restart of Mathematica works. This is in the notebook version of the book. I'm using Mathematica 13.1 on Debian 11. Also, this exact same behavior happens on the Wolfram cloud version of the book, and there it hung my notebooks for longer since there's no easy analog of reset; I think I had to do some random things that I no longer remember in order to get my web notebooks to work again.
