Keys and mouse buttons are sticking

Playing the game in continuum, I find that they keyboard and mouse keys very often become stuck. It doesn't seem to matter how short or quickly you press the keys/buttons. It appears to happen randomly and it makes the game very hard to play.

What I mean by "sticking" and "stuck" is that the game continues to read a key or button as if it were being held down, even though it is not being held.
