[lazarus] Does LMEraseBkgnd message work?

[Tony Maro]

I'm trying to use:

procedure TFrmAbout.LMEraseBkgnd(var message: TLMEraseBkgnd);
begin
  Message.Result := 0;
end;

to prevent the window from automatically blanking the background (for
forms I'm drawing myself) and it doesn't seem to work.  You still get
the cool gray flicker of the form.

Thanks,
Tony
