    RB 7.x contains modifications to ensure thread-safety. Eliminating the use
    of ppParentWnd was necessary for thread-safety.

    If you have a windowed control that you need to use, create a descendant
    class that overrides the CreateParams method and add the code shown below.
    You can then create an instance of the descendant class and leave the Parent
    property unassigned.


    procedure TmyWinControlDescendant.CreateParams(var Params: TCreateParams);
    begin

    inherited CreateParams(Params);

    Params.Style := Params.Style and not(WS_CHILD);

    end;
