ACC: Locking First Record Also Locks Last Record

MORE INFORMATION

Steps to Reproduce Behavior

1. Start Microsoft Access on two different computers and open the sample database NWIND.MDB.
2. On both computers, choose Options from the View menu.
3. On both computers, select Multiuser from the Category box.
4. On both computers, select Edited Record in the Default Record Locking box.
5. On one of the computers, open the Customers table. Edit the first record by adding enough characters to each field so that each field is the maximum allowed length. This will force Microsoft Access to store the data on the last data page.
6. On the other computer, open the Customers table, move to the last record, and try to edit the record.

Note that compacting your database periodically will keep the data in order on the data pages, which should help prevent this behavior from occurring.

Note also that if all the records in a table are locked when you choose the Edited Record option it means that all the records fit on one data page, and therefore if any record is locked, then all the records are locked.
