 Last reviewed: April 30, 1996
Article ID: Q131041
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.
