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.
