Hi all,
I've been working on fixing the crash in 'Gens' when trying to reassign keys.

The app basically does a:

while (1)
{
 IDIRECTINPUTINTERFACE::GetDeviceState();
}

Until it notices a key has been pressed.  DirectInput hooks onto system 
keyboard events with SetWindowsHookEx(WH_KEYBOARD_LL........), but while the 
app is doing its nasty while(1) loop, DirectInput's callback procedure never 
gets called.

This is as far as I can get  (new to wine) - any ideas anyone? I threw a test  
case app that illustrates the problem

(btw, the WH_KEYBOARD_LL hook has the note 'should use SendMessage instead', 
but I don't get what this means or know if using SendMessage instead would 
have anything to do with fixing this problem)
