Buffering = 4 (pessimistic) means that VFP will try to lock the record as soon as it's updated. That means that nobody will be able to modify this record until the user save the modification. If you don't want this behaviour, change the buffering to 3 or 5 (optimistic). You will have to deal with collisions on the updates however.
