Broken arrow keys?

Question

For some reason, the down and right keys aren't working. They work fine in other programs but in this program they fail. What's going on?
paddle_ybase = paddle._yscale;
paddleSpeed = 0;
onEnterFrame = function(){
if(Key.isDown(Key.UP)){paddleA._y -= 1;}
if(Key.isDown(Key.DOWN)){paddeA._y += 1;}                    
if(Key.isDown(Key.LEFT)){paddleA._x -= 1;}
if(Key.isDown(Key.RIGHT)){paddeA._x += 1;}                  
steam(7);
paddle._rotation = paddleSpeed;
function steam(num){
for(i=0;i<num;i++) {
    var k:MovieClip = boiler.attachMovie("air","air"+i ,boiler.getNextHighestDepth());
    k._y -= Math.random()* (100 + num);   
    k._x += (Math.random()* 10 -5) * (Math.random()* 10 -5);           
        k._rotation += Math.random()* 90 - 45;
    k.gotoAndPlay(Math.ceil(Math.random()*16));   
    k._xscale = k._yscale += Math.random()* 177 - Math.random()* 100;
    if(k.hitTest(paddleA)){paddleSpeed++;}

if you're testing in the flash test environment, disable shortcut keys.  retest.
