VBA Code to stop Access 97 db converting to Access 2000

Hi

I have written a database in Access 97 that uses replication.
I have recently discovered that some users have Access 2000 and that it does not givew the option to just open the db but just gives the option to convert it.

I'm afraid if it is converted access 97 users would not be able to use it.

Is there any way that I can include code in my db to stop the db being converted, something that automatically just opens the db without prompting the user.

Any help would be mmuch appreciated.

thanks

Cooks.
