Ugh. Does single-app mode really reuse the retail mode login path?

[stevenjb, 2013/04/03 17:21:42]

I'm not sure I understand the question, but I copied the logic from
SystemTrayDelegate.

[Nikita (slow), 2013/04/03 17:48:13]

I think these two should be separated.

DemoUser = retail mode (previously known as kiosk mode).

KIOSK_APP = single app mode (new definition for kiosk).
