What steps will reproduce the problem?
1. using example in JNativeHookDemo, can see that when pressing pause/break it 
instantly shows released even while still pressed.

Should not see native_key_released trigger until button is released, instead 
shows native_key_released immediately after pressed.

Doesn't seem to be happening any more after reboot, not sure what caused this.

Hi Michael, 

There have been some interesting things happening with the low level hooks on 
Windows >= Vista.  I still don't know exactly what is causing the problem, but 
it looks like other programs maybe interfering with the hook for some reason.  
I have started work on version 1.2 which will externalize the hook from Java 
allowing for much simpler debugging.  Once that is done I will see if I can 
better determine why this is happening.  If you notice the problem again see if 
you can figure out if there is a program running that maybe triggering it or 
how to reproduce it.

Thanks for the report.
Alex Barker

One other thing, what languages do you have configured and which one is the 
default.

That's a keyboard hardware feature, and cannot be worked around in any 
software. See http://www.win.tue.nl/~aeb/linux/kbd/scancodes-1.html#ss1.1

"The [pause key] produces scancode sequence e1 1d 45 e1 9d c5 when pressed 
(without modifier) and nothing at all upon release"

notice that 45 is a make code and c5 is a break code for the same scancode 
(c5h=45h+80h).

Rather, it's strange if it doesn't give a release code right after pressing.
