I am trying to make the currently selected window a bit easier to recognize. So I right-click the desktop, "Personalize", clicked "Window Color" => Advanced Appearance settings, selected "Active Title bar" and picked a dark red as one of the two colors. This should yield me a red-blue title bar and so it also shows in the preview.
But when then I click Apply or OK, the desktop goes gray for a while and then comes back in colors, but the active window's color has not changed at all! It's still in blue...
What am I missing? Why does the current schema (Aero Themes / Windows 7) not accept my customization?
