I don't have the files with me right now, I will try tomorow.
But the strange thing is that it not happen with the previous driver.

Well, I have a couple of delphi componentes that talk directly
to the driver bypassing the BDE (because I hate to distribute the BDE),
and it say is for Odbc 3.
See the attachments, I've managed to convince the author to release
the source in the next version :)

The same here, all the components (Odbc98, OdbcExpress) expect (or work
better with) scrollable cursors in the driver, but I guess I can live
with this.
