ZombieEscape: Multiple KeyBinding at one moment?

Hi Guys! Unome again. The JavaApplet I've been working on is becoming a killer success. My character now has an environment it can explore. He can jump, run, crouch, heal, commit suicide, pause, restart.... and a variety of other things... My main problem at the moment is this:

I cannot perform multiple actions at once:

Situation: Player is pressing the forward key, and then strikes jump(still holding forward key)
RESULT: In normal games you would jump forward... When I strike the jump action the forward action is canceled and he jumps straight up.
HOWEVER: If I strike the keys at the exact same time (kinda hard) he jumps forward.

Same priuncipal apply's when firing gun, jumping, crouching, healing ect...

Heres my action code:

Code:

---

......................
....................
private void bindKeys()                        //sets up key actions for the program
        {
                JRootPane rp = getRootPane();
                int c = JComponent.WHEN_IN_FOCUSED_WINDOW;
                InputMap inputMap = rp.getInputMap(c);
                ActionMap actionMap = rp.getActionMap();
                inputMap.put(KeyStroke.getKeyStroke("LEFT"), "LEFT");                //creates left action
                actionMap.put("LEFT", walkleft);
                inputMap.put(KeyStroke.getKeyStroke("RIGHT"), "RIGHT");                //creates right action
                actionMap.put("RIGHT", walkright);
                inputMap.put(KeyStroke.getKeyStroke("SPACE"), "SPACE");                //creates space action
                actionMap.put("SPACE", fireball);
                inputMap.put(KeyStroke.getKeyStroke("P"), "P");                //creates space action
                actionMap.put("P", pause);
.............................
.............................
............................

private AbstractAction walkleft = new AbstractAction() {                //action that moves the ball left
                public void actionPerformed(ActionEvent e) {
                    Moveball.moveleft();

                }
            };

            private AbstractAction walkright = new AbstractAction() {                //action that moves the ball right
                public void actionPerformed(ActionEvent e) {
                    Moveball.moveright();
                   
                }
            };

I think the trick lies in the "WHEN_IN_FOCUSED_WINDOW" I'm not quite sure though.

Mmk Java Jenius's. Can you solve this error?
