[Geekos-devel] Need help with GeekOS.. project 0

[Joshua G. <jos...@gm...>]

Well, I hope I don't come across as a complete noob. I'm working on 
project 0. Every time I use Wait_For_Key, it returns a pressed key 
/twice.   /So if I press "f", Wait_For_Key returns it twice. I've also 
done some debugging and the Keyboard_Interrupt_Handler also is called 
twice. I'm testing in Bochs and also on real hardware and I get the same 
result on both. Help?

Keypress events are generated for both key presses and key releases.  
Check for
the KEY_RELEASE_FLAG being set in the keycode - those are releases,
which you should just discard.
