Zeh,

Thanks for that answer! This answers a lot of questions! Simply said,  
useFrames does not make a lot of sense in common daily tweened  
animations,
unless you want to make sure that your rendered all the frames in that  
given situation, this gives me a lot of ideas from what you have told,  
never thought about
PRERENDERING some stuff into btimap and use those later! Great idea  
btw! This would make some heavy sfx that normally eats-out the cpu run  
smooth, wow,
i never thought about that in this terms!

Zeh, you got any live examples of prerendering animations into bitmaps  
with tweener?

What kind of "optimization" should i consider when animating a lot of  
stuff on screen?

I know that's a bit off-topic, but you got the experience and  
knowledge i definitely lack :-)

Cheers,
Patrick
