To hide the complexity of most of my systems. I try to make the line items (that is, a standard one-to-many database) where they will not be stumbled opon by the users. Since most of the time they are not ment to me viewed by the users.

The best way i have found is to:

-Put the line item is another folder in the same directory as the master file.

-In the startup script for it, and have a Toggle Window [Hide]

What other methods do people use?

I have found that a simple "dialog" screen works best. Something like a 320x320 layou with a message that this is a supporting file and contains no user interface. The entire layout is a button which hides the window and/or sends the user to the main menu.
