I saw a Borland employee reply there a couple a weeks ago that the MySQL transaction support is coming to dbExpress. Since Borland is marketing their own database Interbase, they have somewhat conflicting interests here. I believe feedback to Borland or their newsgroups can speed things up. > -- > John A.
