Connecting to an Access table with a memo field using ODBC

I am having problems connecting to an Access table containing a memo
field using ODBC.  I can connect without a problem to that table using
the native driver.  I also have no problem connecting to other access
tables (tables without a memo field).  I get the following error message
: "invalid string or buffer length" followed by an unreadable sequence
of characters.  I'm using D4 and Access 97.  Has anybody run into this
problem?  Thanks in advance for your help.
