Running USE test; query with AJAX does not have expected results - database is not changed as it used to.
Also when running "USE fdasfasdfas;" (or any non existing database name), the error messages just quickly flashes on the screen and nothing happens.
Changed the subject line as it's not working when js is disabled.
Changed the group as it's not working in 3.3.6.
This bug was fixed in repository and will be part of a future release; thanks for reporting.
