I have a situation with a form that is populated with a query that uses 2 tables. Example: table1 uses 7 fields and table2 uses 3 fields, these fields are both text fields as memo fields and a key field that uses the key field in table1. Table1 fields are 2 text 4 numeric and 1 key field. Every so often one of the memo fields will delete its data for no apparent reason. How do I track down what is causing it?
