MSaccess97 instert & memo

Running pgsql on a Linux box, accessing it from a Win95 machine with
Access97 using Postdrv 6.30.  When ever I link a table from the database
into access that has a data type of memo for one of the columns I can't
insert.  I have the given the right permissions to the table with the
grant command in psql.  Is there a way around this problem?  And I must
use Access for the frontend.

Thank you

Shane
