Windows

Hi all,

My hardware has a problem, from time to time it's sending a "keydown" followed by a "keyup" of event:

keydown: None LButton, OemClear 255

keyup: None LButton, OemClear 255

keydown: None LButton, OemClear 255

keyup: None LButton, OemClear 255

It goes like this forever, in Windows.

In general it doesn't affect most of the applications, because this key is not printable. I think it's a special function key, like a media key or something. It doesn't do anything.

But, in some applications that LISTEN to keydown and keyup, I get undesire and unexpected behaviour.

Is there a way to intercept these 2 events in Windows (for all applications, for Windows itself) and make the OS ignore them?

This is really important to me, if you can think of any solution, I'd be forever thankful.
