Steps to Reproduce Behavior

  1. Create a program with the following code. 
          CLEAR
      CLOSE DATA ALL
      CLOSE ALL
      SET EXCLUSIVE ON
      SET SAFETY OFF

      ERASE test.pjx
      ERASE t1.dbf
      ERASE t2.dbf

      CREATE DATA test

      CREATE TABLE t1 (name c(10))
      INSERT INTO t1 (name) VALUES ("test")
      INSERT INTO t1 (name) VALUES ("TEST")
      INSERT INTO t1 (name) VALUES ("test")
      INSERT INTO t1 (name) VALUES ("test")

      CREATE TABLE T2 (addr c(10))
      INSERT INTO t2 (addr) VALUES ("addr")
      INSERT INTO t2 (addr) VALUES ("addr")
      INSERT INTO t2 (addr) VALUES ("addr")
      INSERT INTO t2 (addr) VALUES ("addr")

      CREATE SQL VIEW xx as SELECT * FROM t1
      CREATE SQL VIEW x2 AS SELECT * FROM t1
      CREATE SQL VIEW x3 AS SELECT * FROM t1
      CREATE SQL VIEW x4 AS SELECT * FROM t1
      CREATE SQL VIEW x5 AS SELECT * FROM t1
      CREATE SQL VIEW x6 AS SELECT * FROM t1

      CLOSE TABLES
      MODI PROJ TEST NOWAIT
  2. After running the code, add the test database to the project.
  3. While in the project manager, remove two or three views by selecting the view and choosing Remove.
  4. From the project manager, modify the database and select "Clean Up Database" from the Database menu. This will pack the .dbc file.
  5. Close the Database Designer window, and return to the project. Click on a view.
The error may not be returned on the first view. Click on a few views and the error eventually occurs.
