Hi @philippeb

I use the FME 2019.1.0.0 and my tile bar is White too:

Thanks,

Danilo

This is weird, it was dark for me on Windows 7.

For me on Win7 / FME2019 the titlebar is white as well. I think this is managed by Windows themes? These settings are locked on my workstation so unable to test changes.

The styling of the title bar is handled by Windows itself, not FME.

If you go to the Windows 10 control panel and select a dark theme, then it should be possible.

See for example: https://www.makeuseof.com/tag/5-dark-themes-windows-10/

I think this is the correct answer. Some dialogs used by FME are controlled by Windows. Switch Windows to dark mode and it will be fine. However, I believe there's a specific setting required to set the color on title bars. Not sure why it's separate, but it is.

Exactly @mark2atsafe

I had to change my “AccentColor” key in the registry (thanks to this article) and now ALL my title bars are dark. That's even better!

I'm happy :)
