Have a utility screen with 7 grids on a pageframe. Used to add/update tables that feed drop-down lists in the main app. Form is set to Optimistic buffering. If I go into the data environment of the form and try to delete a record in any of the tables that is used by the CHILD table, the RI correctly catches the error and allows me to revert. However, when I run the form, I can only get 5 of the grids to do this properly when I DELETE a like record. Thinking the grid was corrupted, I would re-create it and it would work, BUT then one of the other grids would begin exhibiting the same problem. Have I hit some limit?
