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

- Microsoft Visual FoxPro for Windows, versions 3.0b, 5.0, 5.0a, 6.0 
-------------------------------------------------------------------------------

SYMPTOMS
========

When accessing the Class Browser, Visual FoxPro may return the following error:

  Invalid buffdirty call

And then Visual FoxPro quits.

CAUSE
=====

Possible causes of this problem are a corrupted Browser.dbf file resulting from
an abnormal termination of Visual FoxPro from a power outage, a computer lockup
or restart, and turning the computer off without properly shutting it down.

RESOLUTION
==========

There are two ways to resolve the problem.

- Delete the two files, Browser.dbf and Browser.fpt.

  CD (HOME())
  ERASE browser.dbf
  ERASE browser.fpt

  NOTE: these two files are created if they do not exist when the Class Browser
  is run.

- Zap the Browser table.

  USE (HOME() + "browser") EXCLUSIVE
  ZAP
  USE

  This clears any corrupted records in the table and prepares it for initial use
  again.

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

The Invalid buffdirty call is not limited to the Class Browser.

Additional query words: Class Browser, GPF, buffdirty
