There is no reaction after selecting the point

[weililiuo]

I didn't get any response from "right click to select Mid-Patella" under the right click of "measure", resulting in failure to "generate measurement file". May I ask why? I saw "TODO" as shown in the figure in the source code of ampscanGUI.py. May I ask whether the code is not perfect and caused by the lack of response? I really hope you can help me solve this problem, which is very important for a college student, thank you very much!!
