A team in our office has a problem with their Access database. When more than one person is working in a particular table simultaneously (one is entering information and one is verifying the data entry), the first person to close the table gets a dialog box saying "Another user has changed the layout of the table. Do you want to save your changes, or keep the other user's changes?" The problem is that both users' changes need to be saved. It seems like this should be possible, since they are never working in the same record at the same time, just the same table. They are not adding or deleting fields, just entering information in existing fields. Can anybody explain what's happening here and how to prevent it?
