Allan,
Opening a Default DS form from a Private DS form will cause the "child" form to run in the same DS. So it is using the same set of record pointers. If you do not wish to have this behavior then you need to set the second form to use it's own Private DS.
>I have created 2 modal forms (Form1 and Form2). Form1 datasession property was set to 2 (Private), while Form2 is in Default. In Form1 open the form Form2 using 'do form'. 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.
