Thanks - the problem occurred after we stopped getting the read errors due to the mapping problem. I can see where the problem I am seeing happened a few times before, but only once since changing from using the mapped drive.

It is really strange - I can open the table, set the order to the order number, then seek the number that had the problem, and it takes me to a record that should have the order number in it, but the order number field is blank. Does anyone know what sequence FoxPro updates tables/indexes? I always assumed that it added the record to the table then updated the index. This looks like it somehow updated the index to reflect what is supposed to be in the record, but didn't get the data in the record....
