AutoCloseTables is set to default (.T.) ... one main difference between your test and my app: While the table is opened in the parent DS, it's only used as the RowSource in a combo that is bound to another table.

>I just tested this on my VFP 6 SP3. The only way I got it to work without an error is to have [obviously] AutoCloseTables set to .F. in the parent form. I bound a control to the same field on both forms. When I switched back the the parent, it showed the data I had navigated to in the child form. I closed the parent and the child worked or failed based on the AutoCloseTables property setting. I did not bundle these 2 forms into an app with a Read Events.
