Tweenlite and Papervision Strange MouseEvents

Hey there
If got a strange problem.
I made a spiral in pv3d using a mc for material and added a listener for the mouse events.
Now the problem is that when i rollover my mc the rollover tween start and directly start the roll out tween.
The clickhandler is rendered useless.
So before adding tweenlite to the class everything works fine
any idea what is going on here ?
