I am running Access 2010. The datablase is split with front end running on my machine and the back end on the server. I have 4 other users using Access Runtime. My settings are set to "Shared" with "No Locks". The users on runtime can use the database with no warnings however if they have the database open and then I open it I get the warning "you do not have exclusive access....." It may have something to do with the fact that today I was making some changes and someone popped it open on me through the runtime. Anyone have any ideas on this. Thanks in advance. Please go easy on the code talk because I don't understand it.
