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

Steps to Reproduce the Behavior

  1. Create a table in Microsoft SQL Server 7.0 by running the following script in the SQL Server Query Analyzer:
       Use pubs   go   CREATE TABLE [dbo].[TABLE2] (      [TABLEid] [int] NULL ,      [ID] [int] IDENTITY (1, 1) NOT NULL ,      [BitField] [bit] NOT NULL ,      [Data] [text] NULL    ) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]   GO					
  2. In a new database in Access 2002, create a link to the SQL Server table that you created in Step 1, and then select the ID field as the primary key.
  3. Open the linked table in Datasheet view.
  4. Type 1 in the TABLEid field.
  5. Click in the Data field, and type or paste 3000 characters or more in the field.
  6. Commit the record.
  7. Expand the Data field, and then click in the field to create a blinking mouse pointer.
  8. Press the DOWN ARROW key to scan through the text in the field.
  9. After several seconds of pressing the DOWN ARROW key and moving through the field, note that question marks appear around the 2000th character.
