Well gentlemen @skysail @monsoonrat, I found the malfunction without creating a new account. As far as I’m concerned and recommend to the Navigraph team is that you need to review the app (Navigraph Charts) a bit because as per the title of the Post “it shouldn’t work this way”
You are ready?
The solution is to make sure that this option is checked: (see screenshots for greater clarity)
- System → Advanced system settings → Advanced → Performance → Settings → “Animate controls and elements inside windows☑️”.
@skysail I deserve a free subscription 
You’re Welcome guys. I wish you a happy weekend and happy flights
