it sounds like you want to keep your users from viewing the database window.
click tools | startup | uncheck the "display database window" checkbox.
There are some other interesting options there also which you should try on a
*COPY* of your database as you can lock yourself out. You can view the
database window by pressing F11 (as your users can also if they know it.).
Here's a link to Albert Kallal's website which you should search for "bypass
shift key".
Or, if this is all elementary to you and I have totally mis-understood your
post (my wife says I do this all the time), I apologize.
