User Interface
There is currently a Locale Selector in the Options --> Account menu. DO NOT USE THIS SELECTOR! This was not supposed to make it into our Beta build.
Workaround - If your game gets messed up because you used this feature, delete your Battle.net folder from your main harddrive/My Computer/ProgramData folder.
