All the tables are row buffered (3).

>>Maybe you can help with a related issue. Several of the tables in the dbc have update triggers set to call this logging routine. Something is firing the update trigger whenever the record pointer is moved even when no edits have been made. In my controlled tests this should not happen. I have searched the entire project for explicit tableupdate code and can find none that should be executed with a simple move of the record pointer. Can you help me figure out what is causing the trigger to fire? Debug is no help.
