David,

Thank you for the explanation, but the reason why i make Form2 DS to Default is because i run a report form which uses the DS of Form2. Setting the Form2 to Private will cause the form not to find the tables it needs.

I've notice, in Data Session dlg. box, that Form2 uses same DataSessionID no. which is 2. And i when exit Form2, Form1 DataSession became 'Unknown(2)', and the index and rec. pointer of the tables was altered.
