Filemaker databases can be designed to open without the Filemaker design and navigation tools showing. Custom Menus can be created with whatever names and contents you desire. If the navigation tools are not shown, you must create the required navigation in the database.
Databases can be created to run in Kiosk mode, whole screen is taken over and ONLY your design is displayed. If you do this, you must include a way to escape and close the kiosk mode database.
The kiosk mode requires Filemaker Pro Advanced, I think.
