>If VFP creates the view as just a filter on the tables in the query, then it seems reasonable to have to close the view before the source tables. But if the view is created (in VFP 5, not sure about VFP 3) with the NOFILTER clause in the select statement, then the view is a temporary table that should not be dependent on the source tables being open. But, since NOFILTER would create such a temporary table written to disk, you take a performance hit. I am not sure buffering had anything to do with it.

This is a 3 tables view. I don't think a filter can be applicable here.
