Ok....I have pretty much done what needs to be done and the I was required to do (I hope) but the one thing I am having problems with is locking down the GUI so no one can get into the other screens behind it. I have password protected it...but I don't want anyone else to be able to load anything on them.

Does this make sense? I am referring to the other screens apps can be running in if you hit the cnt'l-alt-F1 keys together to get another screen (hit any of the function keys I mean). Only one screen gets you into a DOS looking area, another a GUI area where my app is running but the other areas I was told need to be unaccessible as well. Is there a way to lock them down?
