fetching way too much or too often???

we have about 20 folks linked to a postgres 6.4.2 database through
msaccess97 and the latest odbc driver. we have declare/fetch turned on.
we are having a problem with the database locking up often! i am trying
to eliminate the possibilities / theories, and i am on the declare/fetch
process now.

when a user selects one record, as a watch on the debug window (started
postmaster w/ debug 3), it is processing many (25-50? who can count that
fast??) fetch 100's -- but they only selected one record from one table!
why so many fetch 100's?? should i turn off declare / fetch on everyone's
odbc??

thanks! jt
