when i built my Application(with TcxDBExtLookupComboBox component ) and try to input for example "A" for searching something like "A" then i got

runtime error message "Stack overflow"

unit:cxControl ,line 2598

procedure TcxControl.MouseMove(Shift: TShiftState; X, Y: Integer);
var
  AAccepted: Boolean;

  procedure SetCursor;
  var
    ACursor: TCursor;
  begin
    ACursor := FDefaultCursor;
    Cursor := GetCursor(X, Y);
    FDefaultCursor := ACursor;
  end;

begin
  SetCursor;
  inherited;
  if (DragAndDropState = ddsStarting) and not IsMouseInPressedArea(X, Y) then  // something wrong??
    BeginDragAndDrop;
  if DragAndDropState = ddsInProcess then
  begin
    AAccepted := False;
    DragAndDrop(Point(X, Y), AAccepted);
  end;
end;
