Hello @ChevalMonsieur, thanks for reporting this bug. Could you please check whether the app works as expected when you run the neu run command again?

This is what i got when trying to recreate the bug on a new app :

In the app

In the inspector

I don't remember why it bothered me but i guess it has something to do with the Neutralino API.

Thanks for checking. Ah, I guess the issue is that the @neutralinojs/lib NPM module was not the latest in the template when you download it in the first time. I think it should work if you create a new app with the latest CLI version :)
