OpenOffice: SetPos with data_at_exec not yet supported

Greetings! Intermittently, but not regularly (unfortunately; those
errors are the most notoriously difficult to pinpoint), when browsing
records which were pulled into OO from a PostgreSQL database via the
Postgres Windows ODBC driver, the error

SetPos with data_at_exec not yet supported

pops up. If you confirm the dialog which displays this error message,
and try to browse to the next record, you get a second one:

Only SQL_POSITION/REFRESH is supported for PGAPI_SetPos

If you confirm this dialog too, and try to move to the next or previous
(or first, last ... ) record, it'll pop up again. The only way to get
rid of it is to press the 'Undo: Data entry' button. Sometimes this
won't work though; what I do then is press 'Undo: Data entry' first, and
after that a button on the form that I've created (which opens another
document). Now I can continue browsing records. This doesn't make any
sense to me.

It would seem that sometimes OO thinks I'm trying to update
some record in the database although all I am doing is pressing the
'Next Record' button. At first I thought that the follwing stuff in the
ODBC driver's log file was corresponding to the error, but it doesn't -
this message also regularly appears in the logfile when the error
message doesn't pop up:

I am using OOo 1.1, PostgreSQL 7.4.1, the PsqlODBC driver
7.03.02.00, and I've set the 'Updatable Cursors' DSN option to 'On' -
which is an idea I've got from

http://archives.postgresql.org/pgsql-odbc/2003-04/msg00014.php

Any ideas?
