  ****************************************************************
  After installing PCOM 6.0.5 Refresh Pack, the user may see
  high CPU usage (20-25%) by PCSWS.EXE process in Task Manager.
  Not all operating systems exhibit this symptom. It is more
  pronounced in a virtual environment with multiple monitors.
  
  This is caused by EnumProcessModules() function call checking
  for the existence of PCSCM.EXE.
  

Problem conclusion

• PCSWS.EXE has been changed to only check for the existence
  of PCSCM.EXE using EnumProcessModules() function when the
  session window gets focus.
  
  Fix scheduled for PCOM 6.0.6 Refresh Pack
