From 56471f14db710f9368a53fa709fe79465220f245 Mon Sep 17 00:00:00 2001 From: Stefan Reinauer Date: Tue, 2 Sep 2008 09:35:43 +0000 Subject: The keyboard driver mixed up the key press/release events for the special keys. Patrick Georgi explained: The |0x80 codes are "break codes", that means, codes that are emitted when the key transitions from pressed to non-pressed, so the modifier was always in the wrong state, as soon as you pressed shift for the first time.
