In our office we use a FileMaker database. However there are two people who use it and one can't tell if the other has the database open. This causes problems if both people are adding or changing data. I realize this is not a server so two can't use the same file at the same time. However, it would be a great help if somehow we can tell on the list if it is opened already. I think it works for Microsoft products. Could FileMaker 11 be added?
