The information in this article applies to:

- Microsoft Visual FoxPro for Windows, version 3.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

After installing the new versions of the 32-bit files for Visual FoxPro,
products such as Microsoft Word, Microsoft Excel, and Microsoft FoxPro start
crashing.

CAUSE
=====

The computer may have a third-party virtual-device driver installed.

RESOLUTION
==========

In the [386Enh] section of the SYSINI.INI file, set the MaxBPs to 400 or
greater.

STATUS
======

Microsoft is researching this problem and will post new information here in the
Microsoft Knowledge Base as it becomes available.

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

The following information was taken from the Microsoft Windows for Workgroups
version 3.11 SYSINI.WRI.

  [386Enh] Section Settings

  The [386Enh] section contains information used for virtual-memory
  page swapping; virtual-memory network drivers; and 32-bit disk
  -----------------------------------------------------------------
  The [386Enh] section can contain the following setting

  MaxBPs=<number>

  Default: 200

  Purpose: Specifies the maximum number of break points (a method for
  transferring control to Windows running in 386 enhanced mode) that
  can be used by the virtual-memory manager. You may need to increase this
  value if you are using a third-party virtual-device driver that requires
  more break points than the default value.
