KeyListener Problems with Directional Key events

Question

Here's the problem: If I press and hold the up and right directional keys (non-numpad) and then press the left directional key, it doesn't recognize that I pressed left (i.e. "LeftKeyPressed" is not printed). What's up? Is there something I don't know about directional keys that makes them special like this? Thanks.
Here's the code:
public void keyPressed(KeyEvent e)
     if(e.getKeyCode() == 37)
               left = true;
               System.out.println("LeftKeyPressed");
     if(e.getKeyCode() == 38)
          forward = true;
     if(e.getKeyCode() == 39)
          right = true;
}

Answer 1

So you want to hold the up key and the right key down and then also press the left key down, but the left key will not activate when the up and right key are pressed and held down first.
You might be at the point that you should ask yourself -- why do I want to have a left key event happen when I already have a right and up going on. It's obviously not for directions, you cannot go left and right at the same time.
