>I'm thinking I would like to shut down my reservation app if it is not used for a while (say 15 minutes). I'm using a file server and my philosophy is that the fewer clients that have files open the better. I would probably go to some minimal state where the app is still running but no tables are open.

I can't speak about VFE, but generally the way I see this handled is that the different object (forms, controls, etc) report each action to the application object. If the application object does not detect activity for some period of time, it shuts down the forms and shuts itself down.
