The user usually has a primary pageframe displayed because it contains client information, telephone log, shipping,etc. This form is set to private datasession.

The user can select other forms: Work In Progress, invoices, payments, etc. If the primary form is open, the other form opens using primary's datasession...if not, it uses default.

The problem is, the user accidently closing the primary form when its datasession is being used by a second form.

How can I prevent this from happening?
