You enable the shift bypass by reversing the code used to disable it
However, developers should normally only need to work on the ACCDB file therefore will only rarely, if ever, need to look at tables & queries in the ACCDE file
My suggestion would be as follows:
Assign permission levels for standard users & developers.
This means people will need to login to your database with user name & password
The user level will then be detected at login
Add code to check the file type ACCDB or ACCDE.
a) If ACCDB, enable shift bypass.
b) If ACCDE, disable shift bypass for standard users but enable it for developers
NOTE The database will need to be closed, reopened & closed again before the shift bypass code will be fully implemented
Good luck
