    * PROBLEM DESCRIPTION: CPU usage by PCSWS.EXE is high after    *
    *                      upgrade to PCOM 6.0.5 Refresh Pack.     *

    * RECOMMENDATION:                                              *
    ****************************************************************
    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
