checkCollisions should return strongly typed Object about collisiondetectionkit HOT 3 OPEN

Agreed.  This is a change I would have liked rolling into the last update but 
was 
overlooked.  Will be done for next release.

You keep this up, Mike, and I'm going to have to start subversioning.  ;P

There are lots of more places in your code where strong typing is pleased. Start
subversioning :-P.

I just made some changes in findCollisions() to support strongly-typed 
parameters.
I find this helpful because I can keep strict mode and all warnings.

protected function findCollisions(item1:DisplayObject, item2:DisplayObject):void
{
    var item1_isText:Boolean = false, item2_isText:Boolean = false;
    var item1xDiff:Number, item1yDiff:Number;
    if (item1 is TextField)         
    {
        item1_isText = ( TextField(item1).antiAliasType == "advanced") ? true : false;
        TextField(item1).antiAliasType = ( TextField(item1).antiAliasType == "advanced") ? "normal" :  TextField(item1).antiAliasType;
    }
    if(item2 is TextField)
    {
        item2_isText = ( TextField(item2).antiAliasType == "advanced") ? true : false;
        TextField(item2).antiAliasType = (  TextField(item2).antiAliasType == "advanced") ? "normal" : TextField(item2).antiAliasType;
    }
