OK, but some clarificaiton still needed. Are you having problems because a
single user (or perhaps multiple users) cannot open mailmerge documents
connected to the same query at the same time, or is it that you want to
select a query and use that as the basis for a succession of merges (e.g.
you have merge main documents a, b, c, and one day you want to connect them
all to query y and the next day you want to connect them to query z) ?
