[AccessD] Composite Unique Key in 2010

[Charlotte Foust]

@David, I always use autonumber PKs.

In this case, when you try to create a composite unique key--and yes, I
know well how to create them--you can set up the composite key, but the
options to set the Primary, Unique, and Ignore Nulls are grayed out, even
for the Primary key when it's compound.

It has to be something in the way their Access is set up, and this was
migrated (by me) from 2003 mdb to 2010 accdb.  I've never encountered this
in other 2010 setups, so I'm baffled.
