ODBC and Access 2000: linked tables problem

I was hoping someone could help me out with this, although
it's probably more of an Access problem than a Postgres
ODBC one...

I am using Access 2000 and postgres, with the postgres ODBC
drivers.

Everything worked fine under Access 97.

Importing tables from the ODBC connection is fine.
*Linking* is fine as far as the table selection and the importing of
fields and selecting of unique index goes.

However, when I try and open the linked table, it says "Access cannot
open the table in datasheet view". Nor can it access it via a query. I
have also tried hardcoding the table in a way which worked in Access 97
(code appended below), and it fails in exactly the same way.

SQL tracing appears to reveal that when a table is opened,
Access doesn't even get as far as putting a command to the
remote database.

This applies to new entirely blank databases. I have uninstalled and
reinstalled Office 2000. I have tried the same thing with the Openlink
ODBC drivers, which also used to work under 97, and now display the same
problem. Nothing has changed on the postgres database. I
have tried it on a different machine, and again it works
under Access 97, but not under 2000. I have looked on
technet/on-line support and posted to
comp.databases.ms-access.

It's driving me bonkers, particularly since there is
obviously nothing wrong with the basic link, as it will
import and link tables, just not open them!

Thanks,

Here's the code I used to link the table...

Public Function CreateTable(Tablename As String) As Boolean

Dim remotetable As String, maintdb As Database, connectstring As String,
tdf As TableDef

remotetable = Tablename


On Error GoTo error
Set maintdb = CurrentDb

connectstring =
"ODBC;DSN=PSQLmaint;DATABASE=maint;SERVER=somewhere.me.here.now;PORT=5432;READONLY=0;PROTOCOL=6.4;FAKEOIDINDEX=0;SHOWOIDCOLUMN=0;ROWVERSIONING=0;SHOWSYSTEMTABLES=0;CONNSETTINGS="

Set tdf = maintdb.CreateTableDef(Tablename, dbAttachSavePWD,
remotetable, connectstring)
maintdb.TableDefs.Append tdf
maintdb.TableDefs.Refresh
CreateTable = True
Exit Function

error:
On Error GoTo 0
CreateTable = False
End Function
