cause an "Internal Consistency Error" message when the report is being previewed
and the horizontal scroll bar is clicked.

Transport the report to the current platform.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at
the beginning of this article. This problem has been fixed in Visual FoxPro 5.0
for Windows.

MORE INFORMATION
================

Steps to Reproduce Problem
--------------------------

1. At the MS-DOS prompt, type the following commands:

         C:
         CD\ 
         MD rpt_test

2. Start FoxPro 2.0 or 2.5x for MS-DOS.

3. Create a table with one memo field and populate the field with data. In
  FoxPro for MS-DOS, type the following commands in the Command window:

         SET DEFAULT TO c:\rpt_test
         CREATE TABLE test_tbl (field1 M)
         INSERT INTO test_tbl (field1);
             VALUES (REPLICATE('W',500))
         CREATE REPORT test_rpt.frx

4. From the Report menu, choose Page Layout. In the Page Layout dialog box, set
  the right margin column to 200.

  NOTE: Setting the Right margin column to 200 is not necessary to generate the
  error. However, it guarantees that the Preview mode will display a horizontal
  scroll bar using video drivers with resolutions up to 1024 x 768.

5. From the Report menu, choose Quick Report, and choose the OK button to create
  a quick report.

6. Move the mouse cursor to the right edge of TEST_TBL.FIELD1 and hold down the
  CTRL key. Drag the mouse to the right edge of the report. You probably won't
  be able to see the right edge of the report form by default. However, when
  the mouse is moved to the right edge of the report, the report will scroll
  until the far edge is reached.

7. Save the report. When prompted to save the environment, choose Yes.

8. Quit FoxPro for MS-DOS and start FoxPro for Windows.

9. Type the following commands in the Command window:

         SET DEFAULT TO c:\rpt_test
         CREATE PROJECT test_app
         MODIFY COMMAND main.prg

10. Enter the following line of code in MAIN.PRG. Then save and close MAIN.PRG.

        REPORT FORM test_rpt PREVIEW ENVIRONMENT

11. Add MAIN.PRG to the TEST_APP project by choosing the Add button. Choose the
  Build button.

12. In the Build Option dialog box, select the Build Executable radio button.
  Then choose the OK button. Accept the defaults, and choose the Build button.

13. After the build process has been completed, quit FoxPro for Windows.

14. Go to Program Manager and choose Run from the File menu. In the Command Line
  field, type the following, and then choose OK:

        c:\rpt_test\test_app.exe

15. When the Page Preview window appears, click the horizontal scroll bar at the
  bottom of the window.

The error message appears, followed by a general protection (GP) fault.
