BUG: Invalid Page Fault When Form Released in Error Event

• Microsoft Visual FoxPro for Windows, versions 3.0, 3.0b, 5.0

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. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
