From a974619978dff4528e810f74fb736cb474db65c1 Mon Sep 17 00:00:00 2001 From: niruiyu Date: Thu, 24 May 2012 08:29:09 +0000 Subject: Remove the check of signature because the code which looks for the input NotifyHandle in the internal linked list is enough. Enhance ConSplitter to register hot keys for new connected consoles.
