Er, sorry change your ShortTimer function to look like this
private function ShortTimer():void
{
// creates a new five-second Timer
if(minuteTimer==null) {
minuteTimer = new Timer(1000);

Yes, it does.
I don't understand why you are creating a timer for 5 seconds and then
starting it again. Why not just create a timer forever?
Just do this,
<mx:Script>
<![CDATA[
import mx.controls.Alert;
private var minuteTimer:Timer = null;
private function nav(myUrl:String):void
{
var urlToNav:URLRequest = new URLRequest(myUrl);
navigateToURL(urlToNav,"_blank");
}
[Bindable]
private var num:int = 1;
////move the visible section of the data grid in focus
private function changeIndex():void
{
entries.scrollToIndex(num);//entries refers to the data
grid below
if (num < RSSfeed.lastResult.rss.channel.item.length){
num++;//increase if thess than the length of
the feed
}else{
num = 1;//set back to 1
}
}
private function ShortTimer():void
{
// creates a new five-second Timer
if(minuteTimer==null) {
var minuteTimer:Timer = new Timer(1000);
// designates listeners for the interval event and the
completion event
minuteTimer.addEventListener(TimerEvent.TIMER, onTick);
minuteTimer.addEventListener(TimerEvent.TIMER_COMPLETE,
onTimerComplete);
}
// starts the timer ticking
minuteTimer.start();
}
private function onTick(evt:TimerEvent):void
{
if(evt.target.currentCount%5==0){
changeIndex();
}
}
public function onTimerComplete(evt:TimerEvent):void
{
minuteTimer=null;
}
]]>
</mx:Script>

Subject: [flexcoders] Re: IE keeps growing and growing and growing
I think it may have to do with calling addEventListener. I think it
may be adding and adding and adding. Is there a way to create a timer
that calls a function every time an interval is reached? I've
experimented with using useWeakReference but I don't see a
difference. Any help would be appreciated.
