some missing details

This is a split db and everyone has their own front end? You dealt with this in every front end and only had to do it once for each? I thought it happens every time you open a protected file. It sounds more like everyone is sharing the same database (We are using .mdb with Windows 7). Beyond needing to be in a trusted location, there really is no such thing as going in and enabling code. Does everything appear normal until you start clicking buttons?
The more we hear silence, the more we begin to think about our value in this universe.
