Well the script shield certainly doesn't seem to be as active it previously was. In XP it is showing 0/0, but if you run windows media player (WMP), boom it does its thing, 106/0. So it is certainly working.
In my win7 netbook it is showing 196/0 (now 213/0) and that is just in the few hours since I updated it and most of that time it will have been idle and I haven't run WMP.
