Under Win10, Delphi 12, TMS VCL UI Pack 13.0.6.0 ( latest ) the TabBackgroundColor of the TAdvPageControl is not appearing with the color as chosen in the Inspector. It appears to be only when a Style has been applied to the project. The same app under Delphi 11.3 with same (13.0.6.0 ) VCL UI it works as required, with the chosen color appearing in the application. Is there a way to get it to honour the color choices as in Delphi 11 ?
