The other think I have notice is I have open exclusive check under tools. But if you look at data session, exclusive is not checked. Could that be causing the problem, because everytime I check it it unchecks itself.

Peter,
In your main program add the following:
set exclusive on

This will override any setting you may have set in Tools - Options. You will also need this in all of your forms with Private Datasessions because the setting is different for each datasession. If you add the tables to the Dataenvironment, then add the code to the BeforeOpenTables event of the Dataenvironment. If you open the files manually in the Load, then put the command in the Load before you open anything.
