SYMPTOMS
========

When you run a 16-bit parent and child program in separate memory spaces of the
parent program, the parent program generates an access violation error message.

CAUSE
=====

This problem occurs because the address space of the parent program contains a
Shared Object list. When you start a child program, it adds its task information
to the Shared Object list. However, when you quit the child program, the child
program's information in the Object List is not removed. The Shared Object list
continues to grow as child programs start and quit until the parent program
generates an access violation error message.

RESOLUTION
==========

To resolve this problem, obtain the latest service pack for Windows NT 4.0. For
additional information, please see the following article in the Microsoft
