SYMPTOMS
========

When you attempt to Check in a file by dragging it to your SourceSafe database,
you may receive an error message, after which SourceSafe will close. If you are
running Windows 95 the message will read:

  "This program has performed an illegal operation and will be shut down"

If you are running Windows 3.x, the message will read:

  "SSEXP. An error has occurred in your application. If you choose Ignore you
  should save your work in a new file. If you choose close, your application
  will terminate"

CAUSE
=====

This error occurs when you attempt to check in or update a file when one or more
of the following conditions exist:

- The file is currently checked out to another user.

- You are attempting the Check-in by using drag-and-drop from the Windows 95
  Explorer or Windows 3.x File Manager into the Visual SourceSafe Explorer.

- The file you are attempting to check in is a sub-project.

- The parent project of the file's project is the active project in the Visual
  SourceSafe Explorer.

WORKAROUND
==========

Do not make the parent project the active project prior to attempting the
check-in.

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

Steps to Reproduce Behavior
---------------------------

1. Open or switch to Microsoft Visual SourceSafe 4.0.

2. Create two new projects using the following hierarchy:

  $/Project1/Project2

3. Add a new file to Project2 and check it out to any directory (this example
  assumes that you have checked it out to C:/Mydir).

4. Close Visual SourceSafe, and then restart it, logging on as a different user
  than that used in steps 1 - 3.

5. Open or switch to the Windows 95 Explorer or the Windows 3.x File Manager.
  Position this window and the Visual SourceSafe Explorer so that you can drag
  and drop files between them.

6. In the Visual SourceSafe Explorer, make $/Project1 the active project, and
  then attempt to drag and drop the checked-out file from C:/Mydir into
  $/Project1/Project2. The error will now occur.
