When I input the Ctrl-Alt-Del key combo(press ctrl, press alt, press del, release del, release alt, release ctrl in that order), it won't see the Ctrl-Alt-Del combo. But when I press ctrl, press alt, press del, release del, press del(at this point it sees it properly), release del, release alt, release ctrl, it does work?

Does anyone what might be the cause of this?
This is the key scancode map used: https://bitbucket.org/superfury/commonemufram … keyboard_data.c

Can anyone see what's going wrong with the scancodes? Or are they correct for the pressed/released keys?
