Hello !🙂

I’m trying to make a simple animation with moving bubbles.  
I am using the hitTestObject method to detect collision between bubbles.  
The problem is that sometime bubbles seems to bounce quite far from other bubbles (about 10 pixels i guess).

You can see the swf [here](http://www.graphea.com/graphea/examples/bubbles.html)

Does someone know why ? Should i use the hitTestPoint for a better result ?

Thanks
