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.
