AdvListEditor popup tab problem

[turhan_orhan]

If lookpopup is showing and if user key press tab key, screen active control is being TListBoxTab. But listboxtab is not visible control, it is not using in advlisteditor.

constructor TAdvEdit.Create(AOwner: TComponent);
.....

begin
.....

  if not (csDesigning in ComponentState) then
  begin
  .....

    with FLookupListBox do
    begin

      .....

      TabStop := true;  <- this line problem

Can you describe with exact steps what the problem is.
When pressing tab from TAdvListEditor with visible lookup, I cannot really see an issue here.
