I don’t know if I should be here, I know nothing else. I have 4K screen. In the program edit window I can change the character size with shift - Mouse wheel. In the other windows (for instance project, message and message windows) that does does not work so the character size is very small how can I change that

I think you have to change the font sizes in the Edit/Preferences ~ General/Custom\_Styles/Fonts.
