Not able to debug in Flash CS5

[Froznic]

I'm able to create breakpoints in my ActionScript File but when I debug (Shift+Ctrl+Ent er) It just prints what it's supposed to without even trying to debug. * are the 2 places I've tried a breakpoint, no-matter where I put it, the computer loops and it prints the numbers from 0 to 10 without pausing or showing anything but the following in the Output window.

Attempting to launch & connect to Player using URL DebugExample.sw f
[SWF] DebugExample.sw f - 2084 bytes after decompression
[UnloadSWF] DebugExample.sw f
Debug session terminated.

Here's the code:

package {
  import flash.display.*;
  import flash.text.*;
  public class DebugExample extends MovieClip {
    public function DebugExample() {
*     for(var i:int=0;i<10;i++) { 
*     showNumber(i);
      }
    }
    public function showNumber(whichNum:int) {
      var myText:TextField = new TextField();
      myText.text = String(whichNum);
      myText.y = whichNum*20;
      addChild(myText);
    }
  }
}
