I've got a database at work that is used by users of both Access 97 and 00. I don't think that someone has tried to convert the database from 97 to 2000, because one can still open the database in 97. The problem is that it will not open in 2000 at all. Even tried saving it as a different name and converting it, but it didn't work. Also the Swithchboard stopped opening on startup in 97. Tried clicking on Tools then Startup and open the switchboard, but when you select the switchboard as the form to open and close the startup box and then go back in the form to open box and it is filled with none. I can understand a 2000 database not opening in 97 due to incapatibility, but why would a db open in 97 but not 2000?
