Odd

- I've never seen any script shield activity on my w7 64bit system with IE9 (32 bit or 64 bit).
There is script shield activity associated with other programs with script activity (such as WMP) though. Is that definitely IE9 browsing ss activity on your w7 64bit system?
If so I'll need to do a bit more digging I think

.
Did you need to do anything to IE9 settings to get it to work?
