As you are using your data entry screens, we are also using them in private data session. But, what I discovered today seems to NOT be private. Maybe I am missing something but here's the situation.
My form is private data session. In the data environment I have a few table having readonly to .T. If those tables are use in another form when adding when this form is up on the screen, I have the message saying "Cannot update the cursor". If I change the readonly to .F., than I can add in the other form. This is non sense. Both forms are private data session and the readonly property is supposed to only affect the current data session.
