General :: Parameter Box Pops Up On Application Quit

When my database application is closed a parameter box pops up asking for parameter from text16 but only if the Navigation Pane is hidden.

Some information:

The application starts with a login screen that has a hidden text box (text16) that allows me to limit what users can access throughout the database by setting it as the query criteria.

If a form is open that is gathering its data from one of these querys and you try to close the application the parameter box opens which is simply annoying for my users who do not know about access.

The interesting thing about this is that if I unhide the Navigation Pane and close the application with one of these forms open it closes fine with no parameter box pop up.

The goal is to have the Navigation Pane hidden and the parameter box not pop up.

Added information if the navigation pane is hidden I can use a command button with a macro that closes all open forms then quits application and this does not cause the parameter box to pop up.

So another fix for my problem would be to disable the "X" close button at the top right of the application.
