Ethan, It seems like you're looking for a programmatic solution to a physical security problem. In the end, your most viable solution will likely be to train Mr. Goodguy to remove the key the same way he needs to remember his ATM card after a withdrawal. I've seen programmatic work-arounds to solve similar issues, but they have always ended up being significantly arduous for the end users... Respectfully, Joshua D.

Mr [Naive] Nice is using the computer, and is logged in. Mr. Ugly just want to "look at" the computer. Ethan-- Joshua - My apologies for an HTML message. That is all I have at work. How about this - Block access to Ctrl-Alt-Del for Mr. Nice. TIA Ethan
