Just posted this on bnet...
I would imagine there's no way this is a client side issue...
but today I accidently (followed up by tests on my end to ensure I wasn't loosing my mind) logged into D3 with cap locks on. That means it's not case sensitve. If this is the case (no pun intended) it would make brute force attacks much more effective.
**** Nevermind, I guess, based on another poster Blizzard doesn't use case sensitive passwords... that, I don't agree with... but, each his own I guess.
