Works for me, though.
Which mysql version?
Is your mysql db / table created with some insensitive "collate" setting?
It should be created with a binary (or case sensitive) collate setting.
Maybe we should change the create database statement to explicitly
include that, instead of putting a BINARY in every sql statement?
Can you check if that works for you, too?
Thanks,
