pg 7.x and Access 2000 -> #deleted error

Hi,

I am using pg 7.x as a db server and MS Access should be the frontend
for windows clients. I installed the newest ODBC driver on the windows
machine. I can link in and open tables from the pg server. But when I
make changes/inserts, all fields of the current record will contain
"#deleted". I have to close and reopen the table to see the newly
entered/changed data.

Any hints to get this working?

Thanks,

Markus
