[AccessD] Access 2007: Compact DB & DB creating copies of itself

Hi,

I have a backend on the server and front ends on clients' machines.  Each
time the client closes the database, it creates a copy of itself.  Both the
front and back ends have the "Compact on Close" option unchecked.

Does anyone have any ideas as to what else could be causing this behavior?
Also, is there a way to just compact an Access 2007 database without closing
and having it rename itself (which Compact on Close does)?  There is an MS
article on this subject, but it doesn't say how to do this in 2007.

Thank you,
Gale
