@Wendell,
That is the solution that Karl posted under the post I pasted if that makes sense. The Windows key and L is great, excpept I tend to not use it, because it involves two hands. (I know!) But for some reason, having only one key to push is much easier -- for me anyway. But, certainly it's a great solution as it is universal.
@Beau,
I can't figure out why multiple users would be an issue. Unless they are running programs where a certain function key does something else by default such as Help on a billing program or something. Usually, you can find one function key that is available.
