Postgres ODBC driver and ms access ole field porblem

Hi,

I have following problem with the ODBC driver or is it the server? I =
have an
MS Access Database which I want to put into a postgres database to have =
MS
Access to be only the frontend. That worked fine until I came across an =
OLE
field.
So I created an lo type in my postgres database as it is described in =
the
postodbc faq.
Now, when I want to access the lo type field in my postgres database =
>from ms
access then I get an error:

"Socket has been closed"

the postmaster log returns something like this:

indExec: found "/usr/lib/pgsql/bin/postgres" using argv[0]
/usr/lib/pgsql/bin/postmaster: BackendStartup: pid 16319 user postgres =

and the odbc driver log returns this:

I am able to put one object into this field, but i cannot retrieve it. I
have to close ms access and to restart the postmaster then I can read =
this
object and the everything is down again.

how can i fix this?

thanks for your help
