I have set up two users for an Access database. One was a guest user with only read only access, the other fill rights. We have been logging in as guest consistently and for some reason the log in screen has dissappeared. It seems to just default tothe Guest log in giving no option to change user. Basically, when you click on the icon the login does not appear and I am automatically signed in as guest. How do I get the log in screen back so I can change what profile I am logging in as?
