Problem with WM_QUERYENDSESSION on NT receiving

At first i am sorry for my english. I run my 16 bit app on Win NT. This app runs some other 16 bit apps as child processes. When i try exit Win NT the main app processes WM_QUERYENDSESSION message and stops Win NT exit.  Child processes don't receive WM_QUERYENDSESSION message, but Win NT informs me the app is not responding. How can i shake off this problem. I have not this problem on Win 95 or  Win 3.1.

You might also need to process the WM_ENDSESSION message.  It is sent to all applications that halted the shut-down process to tell them whether the session was actually closing or not.  There are conditions where an apps denial of the WM_QUERYENDSESSION will not be able to stop the shutdown.
