A system that has more than 15 tables has been working fine for several years. Recently, however, a procedure that updates a particular table does not always save the changes. There are no errors or warnings when the tableupdate is done.

The procedure is based upon a class that is used for all of the other tables and there are no problems with any other table. The table in question is defined in a view with optimistic table buffering.

Usually, the user can shut down the system and re-enter then it will work.

Anyone have any ideas?
