Oh, I thought (perhaps wrongly) Neil was saying that Access's own
locking mechanism wasn't good enough to prevent an insert followed by a
select MaxId, wrapped in a cftransaction, from allowing another insert
query to creep in between.

However, if it is, then -- yeah, to hell with the named lock and just
use cftransaction.
