Hi Trevor. Thank you for the prompt reply and there’s no reason to apologize, it’s all part of my learning experience. I have modified gui.py manually and it all works as expected now. I’ll post updates if I encounter any problems.
I have a (naive) question related to the forum posts. When I posted the code and console capture my post looked much less organized and syntax highlighted than it is now. Have you prettified it or is there an automated process that does it for us? Thanks again.
