That is more then likely the correct action to take for this one:


The problem was being caused by Internet Explorer 6. With automatic script
debugging enabled, it would try to log it's actions and get locked into a
loop causing it to cease responding and lock everything up during shutdown.

The solution was to disable automatic script debugging. There has been no
noticeable effect upon my web browsing after having done this.
