Urgent !!!! Help with VB6/ADO

I have the following code for locking rows that worked fine with VB6/ADO/Ora7.3.4

rs.open "Select * from tab where xx = y for update", conn, ....
....

updates lines
....

rs.update --> ' Unlocking the rows

When the server was changed to Ora8 the same lines fails with the message "Ora-01002 fetch out of sequence"

Any ideas????

Thanks in advance,
