VFP need to lock the header of the table a fraction of a second when adding new record. If another user try to insert a record while another user as a lock on the header, you get a error message.

2 suggestions:
- Turn on record/table buffering and check the result of TableUpdate() (my preffered choice)
- Issue a RLock(0) before inserting the new record and release it afterward. RLock(0) will lock the header of the table

>My users are intermittantly getting a "File is in use by another user." error when they do an INSERT INTO a table in my DBC. There are a few users in the application at the same time. I have SET EXCLUSIVE OFF. This problem did not seem to happen before I added the table to the DBC (was stand-alone before that).
