Hi Gustavo.

>> If you have two tables opened (table 'A' and 'B') and have a grid object to each table, if you set a relation between these tables, the child grid table shows only related records. Until now, ok. But, if you release the relation the grid's of child table continues to show only the related records. It must be a VFP bug. <<

Yes it is. It is documented in the Knowledge base. Check out

SYMPTOMS
When you use the SET RELATION TO command to break an existing relationship, the only records displayed from the relationship's child table are those that are related to the current parent record and beyond. Any child records that match parent records prior to the current parent record are left out.
