Article: Q172815
Product(s): Microsoft SNA Server
Version(s): WINDOWS:3.0,3.0 SP1

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft SNA Server, versions 3.0, 3.0 SP1 
-------------------------------------------------------------------------------


SYMPTOMS
========

The Windows 3.x version of the 5250 applet (Win5250.exe) traps.

CAUSE
=====

When Win5250.exe terminates, it occasionally does not unload Wswappc.dll from
memory. When Wswappc.dll has not been previously unloaded, Win5250.exe traps the
next time it is run.

STATUS
======

Microsoft has confirmed this to be a problem in SNA Server version 3.0 and 3.0
Service Pack 1 (SP1). This problem was corrected in the latest SNA Server
version 3.0 U.S. Service Pack. For information on obtaining this Service Pack,
query on the following word in the Microsoft Knowledge Base (without the

MORE INFORMATION
================

With the fix applied, Win5250.exe allocates global memory with GMEM_SHARE and
this memory is not discarded when the applet terminates.
