Missing ScrollBar in AdvColumnGrid cells

Greetings from the Czech republic,

I have a very simple code for displying scrollbars inside selected cells (with RTF content) in grid and I'm hundred percent sure that they vere visible even recently. Actually, I cannot see scrollbars whatsoever and I cannot find out why.

My code for TAdvColumnGrid is
with Grid3 do for I:=1 to RowCount-1 do AddScrollbar(1,I,True);

Do I have to set any special options for proper displaying the scrollbars?

Version 3.2.0.4 of TAdvColumnGrid.

Thank you for any help.

How can I reproduce this?

I retested this here with a default TAdvColumnGrid on the form and the code:

procedure TForm1.Button1Click(Sender: TObject);
begin
  AdvColumnGrid1.AddScrollBar(1,2);
end;
