title: TPanel color is black no matter what
body: <p>I just activated the themes in my Windows XP (usually I work using the classic Win9x look) and I have seen that two panels are pure black. Other panels are ok (color = clBtnFace).
  What these 2 panels have in common is their parent. Both are placed directly on a TForm. If I move them to a different parent (another panel for example) the have the appropriate color. </p>
