Running FMP 14 on an iMac as host. 3 FMP files on host computer, one of them now opens (not in admin) without asking for password when accessing from host or guest computers, resulting in no security for this file. Other two are okay. Don't know what happened to cause this. Can log in as admin by holding down option when opening file and entering admin and password in dialog box. File->File Options "Log in Using" is off, as I understand it should be to activate the log in procedure. What is going on here?
