Building Password Protection
You can protect a building so that it cannot be saved without a password. When a password protected building is opened, the user is prompted "Note! Saving the opened building requires a password". The program asks a password for the open building only once, when the building is saved for the first time. After this, the building can be saved without the password. When the building is closed and opened the next time, the password is asked again for the first save.
The building's password is set by selecting Archives | Buildings | Maintenance Building Password Protection. The same function is also used to change the password and to remove the password protection.
When a building is password protected, it cannot be saved under a new name either.
