It sounds like the problem definitely lies with the second form. How are you opening / closing tables for this form? Another possible issue is a dangling object reference. You can get the "Alias not found" message from VFP if it tries to destroy a form, but some other code in your app has a reference to the form (or an object on the form) that has not been released. In this scenario, the form's data is successfully closed, but the form and its controls are not released and since the bound controls no longer have access to the data source, you get the error.
