Comment 3 for bug 974610

Let me add "me too" to the list of people noticing this bug. I was going to file a report on it, but a search turned up this list.

It appears that hitting "cancel" at any point of the login, even before entering a username, will make it impossible to log into the system. "Cancel" does not return you to the Username prompt, and you cannot get focus back to where you enter passwords.

Related to this may be the case where you mis-type the username. Again, there is no way to return to a place where you can enter the username again.
