clear ALL Intervals ?

[MyFriendIsATaco]

just push the timers into an array, then loop through the array to clear them all:

var timers:Array = new Array();

var i:Number = setInterval(....);
timers.push(i);

function clearAllIntervals(a:Array):Void
{
   for(var i:Number=0; i<a.length; i++)
   {
      clearInterval(a[i]);
   }
}

with that function, you can then just call, clearAllTimers(timers); and it will do the job.
