Meanwhile, back at the office... I gave this a little more thought.
One thing I noticed in your first post is you were writing the value of 0 instead of 1.
In my last post, I said you had to logoff / logon. Now I'm not so sure. May in fact need a reboot.
I dusted off an old '95 laptop here and tried it but couldn't get it to work.
