I want to know why the 'major follow me' information window doesn't open

I used to open the window, but when I open it again, the information window doesn’t open

What is the ‘major follow me’ window? There isn’t supposed to be any sort of window opening when you start the Follow Me tool. What version of SketchUp are you using? There is no SketchUp fro Schools 2017 as you put in your forum profile.
