>I have a method that changes the .Database property of Cursor objects in the Dataenvironment to point to the correct data folder, rather than my development folder. I have .AutoOpenTables = .F. for these dataenvironments, and do DataEnvironment.OpenTables() after setting the property. I have one form where the OpenTables() was giving me the "Object is not contained in a form" error, which I asked about in another thread. Searching help for insight, I found this:

You are trying to solve it the right way, but someting has gone wrong. Howsabout posting your code that changes the database?
