If one has multiple WoW Accounts attached to a single Battle.Net account, one is not able to get further past the "Select an Account to Copy From" screen after logging in to the PTR website. Once an account is selected, and the "Continue" button is pressed, the same page comes up again.

This does not appear to be a browser related problem, as this problem persisted both on Opera 10.53 and Internet Explorer 8.0.

Thanks for the report. At the moment, it may be that this is simply related to character copy being inaccesible. However, we will investigate.
