I've got a touch screen computer that I'm going to be using as a time clock interface for a small business. It runs Windows 2000. My time clock program runs full screen, but I want to lock it in that position so that the rest of the computer cannot be accessed by pushing (shift + tab). Any ideas on how to do this? I can close the program myself when it is in full screen by using a password. I just don't want anyone else to be able to do it.
