Is there a way to passowrd protect the "settings" so someone can't go in and change them?

I don’t want a user to have the ability to change the settings. Is there a way to “lock them out” while still being able to use the eM Clint program?

As far as I know that is not possible Ken. As the settings file is opened and modified when the application is running, you can’t even write-protect it. Doing that will crash the application on start. About all I can think is that you could have a script to replace the file on Windows start.
