--- Comment #20 from Michael DeVore medv4380@yahoo.com 2012-06-05 23:03:31 CDT --- I can replicate the issue without fully logging in.
I launched Diablo as I normally do put in user/pass then I went to the next room to grab my phone to get an authiticator code. Locks up at retrieving characters and 100% cpu usage.
