Problem summary

• ****************************************************************
  * USERS AFFECTED: All users in an environment where PCSWLIB    *
  *                 is used by a non-PCOMM process.              *
  ****************************************************************
  * PROBLEM DESCRIPTION: PCOM sessions freeze when closing the   *
  *                      3270 emulator windows.                  *
  ****************************************************************
  * RECOMMENDATION:                                              *
  ****************************************************************
  When multiple sessions are started and one by one they are
  closed, the last few sessions freeze and will not respond to
  any window functions.
  

Problem conclusion

• Shared memory for emulation was creating two threads for debug
  purposes. In certain environment where PCOMM's shared memory
  emulation is used by non-PCOMM processes, these threads can
  lead to a hang in PCOMM sessions. PCSWLIB.DLL has been changed
  to no longer create these threads.
