Why not call message_box_->Hide() here?

[kelvinp, 2014/10/31 21:12:53]

HideUi() is called by ContinueSession which is called when the user clicks the
Ok button. The MessageBox will close the dialog when a button is clicked so it
is not necessary.  But for consistency, doesn't hurt to call it here.

Done.
