i have a solution that i have built in which i have multiple users. I run the Filemaker Pro on a windows machine and have the users use iPads. I have it set up to where they have to login through a layout (not through the security options) when the file opens. I have users login to keep track of who does what to records. my problem is that i would like when the app is closed (sleep/hibernating, not closing the "last window") and then reopened to require the current user or new user to log in since i have multiple users use one iPad. i have tried to do this with the fmreauthenticateXX keyword but that only allows the user who was logged in to relogin. i would like once the app is closed and then reopened that anyone can login. Basically i'm looking for a trigger that is fired when the app is reopened. Any ideas or workarounds?
