TITLE   :FIX: Rollback of a Shared File Rolls to Unexpected Version
PRODUCT :Microsoft SourceSafe
PROD/VER::4.0,4.0a
OPER/SYS:
KEYWORDS:kbSSafe400bug kbSSafe500fix

======================================================================
-------------------------------------------------------------------------------
The information in this article applies to:

 - Microsoft Visual SourceSafe, 16-bit, for Windows, versions 4.0, 4.0a 
 - Microsoft Visual SourceSafe, 32-bit, for Windows versions 4.0, 4.0a 
-------------------------------------------------------------------------------

SYMPTOMS
========

When you Rollback a Shared file, the resulting version number may appear to be
incorrect. For example, if your file contains 8 versions, and you elect to
Rollback from version 8 to version 7, the History window will indicate that you
rolled back to version 8, not 7 as expected.

CAUSE
=====

When you Rollback a Shared file, Visual SourceSafe forces a Branch to occur. The
additional version number is a result of the Branch that takes place when a
shared file is rolled back.

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 SourceSafe
5.0.

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

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

1. Open or switch to Microsoft Visual SourceSafe.

2. Select a file that has several versions and share it with another project.

3. Open the History Window, and select the previous version of the file. For
   example, if there are 10 versions, select version 9.

4. Select the Rollback Command Button. You will be presented with a dialog that
   notifies you that Rollback is undoable. Click the Yes Command Button.


5. Note that the topmost item in the History Window is still the version number
   that you rolled back from. The Action column also indicates that you rolled
   back to the version number that you were rolling back from. For example, if
   you were rolling back from version 10 to version 9, after the Rollback the
   History Window still shows 10 versions, with version 10 reading "Rolled Back
   to Version 10."
