I have created an package with "BlackSurface" Theme. When I run the setup wizard, the window header is always white: I have other packages, where the header is black.

Thanks so far!
This did not work for me though. What else can I try to have a black title bar?Eusebiu wrote: ↑Tue May 15, 2018 7:56 am Hi,
I tested your project and, indeed, I reproduced the behavior, but I'm not sure why this happens. Did you modify the project manually in a text editor?
In order to fix it, you can choose another theme, then switch back to the "Black Surface" theme. However, please note that dialogs will be reset to default in the "Dialogs" page.
Best regards,
