           Summary: shift key states accessed at wrong time
           Product: ReactOS
           Version: 0.3.11
          Platform: QEmu
        OS/Version: ReactOS
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: Kernel
        AssignedTo: ros-bugs at reactos.org
        ReportedBy: airstrip_one at ntlworld.com
         QAContact: ros-bugs at reactos.org


When using shift keys (ie Shift, Ctrl, and Alt), their state is picked up at
the wrong time.

Suppose I press Shift+X to get capital X. The status of Shift should be picked
up when X is entered. Instead it appears to be picked up when X is removed from
the message queue.

There can be a delay between the entry of the key and its removal from the
queue, especially (eg) when running ReactOS under Sun VirtualBox. Because of
this delay, the user must continue to hold down the Shift key until the X key
is processed, otherwise he gets X in lower case.

This does not match the behaviour in Windows, and it makes keyboard input
unpredictable if a system is running slowly.
