Hi,

I have a comboBox with an EventListener:

```auto

rhythmTypeListener = new Object();
rhythmTypeListener.change = function(evt) {
	trace(&#8220;run code&#8221;);
}
rhythmType_Combo.addEventListener("change", rhythmTypeListener);

```

All of this works until I select the comboBox’s index programmatically;

```auto

rhythmType_Combo.selectedIndex = 6;

```

The comboBox changes to the approrite text but the EventListener is never called.

Why is this, and is there a way?
