If you installed MySQL 4.1.7 on Windows with the new installer, it will
automatically use InnoDB tables as the default unless you specify different.
(This is different from earlier versions), so the error was probably not in
the Query Browser, but in the server settings in this case.

Assuming you don't need them for replication or point-in-time recovery, you

HOWEVER, there are a few ways you can get around this.
