Crazy that even c9s Logitech keyboards are double registering keystrokes. actually such a common problem with these keyboards. Mines been doing that forever and, because the switches are soldered on and are Logitech proprietary, it makes the keyboard actually worthless.
for the record, typing in korean is an acquired skill and difficult to do when you're used to an english keyboard. they're not at all alike. props to jojo for trying. showmaker just built diff.
