Thanks Scott,

I've tried adding the "WQL","0" as suggested. Rather than setting the
break point, I stepped through it with F8. This shows that the loop is
indeed entered, but only once. The particular line
"ObjOperatingSystem.Win32Shutdown nLogoff" is executed, but nothing
happens. Similarly the same invocation line specifying either reboot or
shutdown DOES work.
