Summary:

PROBLEM ID: WIN9103016

SYMPTOMS
   Using the SwitchStackBack function causes an unrecoverable
   application error (UAE) in Windows 3.0.

STATUS
   Microsoft has confirmed this to be a problem in Windows
   version 3.0. There is a workaround this problem under 
   Windows 3.0 by using the functions NewStack and OldStack 
   provided in the software library sample NEWSTACK which 
   provides Windows 3.0 replacements for SwitchStackTo and 
   SwitchStackBack functions.

   This problem was corrected in Windows version 3.1.

MORE INFORMATION
   The functionality provide by NEWSTACK and OLDSTACK will 
   work in Protected Mode only.  If the functions are called 
   from Windows 3.1, the SwitchStackTo and SwithStackBack 
   functions are called instead of NEWSTACK and OLDSTACK.
   instead. The sample can be found by search for Sxxxx in the 
   software library.
