Мастера - HELP! (Код прилагается). Трабл ---> Когда я кладу на форму мою кнопку, то при движении мыши она (кнопка...) меняет цвет, а когда запускаю прогу - то все нормально. Попробуйте в действии и разъясните пожалуйста, что я упустил.
P.S. И подскажите, как мне сделать для нее CAPTION??????
Я делаю так

var mb:TMButton;
procedure TForm1.FormCreate(Sender: TObject);
begin
mb:=TMButton.Create(self);
mb.Parent:=self;
end;

procedure TForm1.FormDestroy(Sender: TObject);
begin
mb.Destroy;
end;

end.

А вот и код моей кнопки

Посмотри код для TSpeedButton и сделай по аналогии.
