I retype my email twice.... I've spent more times to upload my test application rather than to write it....

Yahoo hates 7z files....

I use :
- employee.fdb,
- 1 x TIBODatabase
- 1 x TIBOQuery
- 1 x TDataSource

The main source code is :
*****************************
    procedure TForm1.Button1Click(Sender: TObject);
    begin
        IBODatabase1.DatabaseName := ExtractFilePath(ParamStr(0)) + '\..\..\' + 'EMPLOYEE.FDB';
        IBODatabase1.Connected := true;
        IBOQuery1.Active := true;
    end;

    procedure TForm1.Button2Click(Sender: TObject);
    begin
        IBOQuery1.Insert;
    end;

    procedure TForm1.Button3Click(Sender: TObject);
    var
        _bk         : TBookmark;
    begin
        _bk := IBOQuery1.GetBookmark;

        IBOQuery1.GotoBookmark(_bk);
        IBOQuery1.FreeBookmark(_bk);
    end;
*****************************

The exception occurs in the GotoBookmark.

My temporary solution used is to replace the Insert by an Append....

kind regards,
