When you try to edit a record in Microsoft Office Access that is being edited by another user, the record may not be shown as locked. Also, Access may stop responding for a significant period of time during the attempt to edit a record that is modified by a user but is not yet saved in the database.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.

When you edit a record in the database by using Access while the record is being edited by another user, all the records that are related to the record are shown as locked. The locked record indicator appears at the record selector of the record, and you may not edit the records.

However, if the record does not have any child or related records, the locked record indicator does not display.

Caution If you follow the steps in this example, you modify the sample database Northwind.mdb. You may want to back up the Northwind.mdb file and follow these steps on a copy of the database.

Steps to Reproduce the Behavior

1. Start Microsoft Office Access.
2. Open the Northwind sample database.
3. Delete all rows that correspond to OrderID 10692 from the [Order Details] table. To do this, follow these steps:

      	[Order Details].OrderID
      FROM 
      	Orders LEFT JOIN [Order Details] 
      		ON Orders.OrderID = [Order Details].OrderID
      WHERE

      SELECT 
      	Orders.OrderID, 
      	Orders.CustomerID, 
      	Orders.OrderDate, 
      	[Order Details].OrderID
      FROM 
      	Orders LEFT JOIN [Order Details] 
      		ON Orders.OrderID = [Order Details].OrderID
      WHERE 
      	(((Orders.CustomerID)='ALFKI'));
      

   5. In the Properties Sheet window, set the Record Locks property to Edited Record.
   6. Save the query as Qrytest.
5. Double-click Qrytest to run the query.

9. Try to modify the Order Date field for the record with Order ID=10692.
   
   Notice that as soon as you type any characters in the record, Access stops responding for a while. The duration of this behavior depends on the number of characters that are typed. However, you cannot modify the record.
