SYMPTOMS

A formset contains a command that releases the form in the form's error event. If the formset is run multiple times and released due to errors, Visual FoxPro will cause an Illegal Operation under Windows 95 and exit to the operating system.

WORKAROUND

Place RELEASE THISFORMSET in the Error Event of the form instead of using RELEASE THISFORM. Then the form will run successfully.

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article.

MORE INFORMATION

Steps to Reproduce Problem

Create a Formset containing one form.
In the Activate Event of the form enter the following lines of code:
```
   ERROR(1705)
   ERROR(1705)
						
```
Add a command button, and add the following command to its Click event:
```
   THISFORM.RELEASE
						
```

In the Forms Error event, enter the following code:

   ? nerror,MESSAGE()
   WAIT
   RELEASE THISFORM

Run the form two or three times. Visual FoxPro will return an Invalid Page Fault error and exit to the operating system.
