Hi,
I have install the latest BC Classic version (I'm on Mac with Yosemite 10.10.3). I have 3 differents BC containers configured. I'm always write my password to open them, if I'm make a wrong password on any of them (not specific to one) Boxcryptor exit and unmount all already BC mounted volume.
I have already send you FULL log on 16/03/2015.
