>I'm using a DBC and there a number of views defined. The application accesses the tables directly. I believe none of the views are updating data, but I will check. The edit screens use most of the typical controls such as textbox, combo, and grid. You had mentioned a grid control on a form they could cause unexpected change to current workarea whenever they have focus. What do you mean by that and could that be my problem?

If I'm not mistaken, any rule you defined in a view only is in effect when you access thorugh a view -- that is, if you access the table directly then none of the rules you've defined in the view will be in effect.

Whenever a grid gets focus, it implicitly does a SELECT (workarea) to the one corresponding to the data source of the grid. This could play havoc with any logic that depends on currently selected workarea not changing.
