Brian,

Thanks for the reply.

While it is possible to have more than one session up on a given client machine (such as multiple instances of SQL*Plus), in this particular case, that is not a factor. The application runs on walk-up "kiosk" -- the PC is in a locked cabinet with only the face of a touch-screen monitor available to the user. The application runs "full screen" and it is next to impossible to get around or behind it to launch *any* other program.
