Hello

I’m slowly rebuilding my site with a Flash and I already have the toolbar, almost title and I thing backgrounds. I have lots of movie clips with shape tweening, button with menus and the problem is that when _I am testing the movie it use 40%-50% of my CPU_ so do you know what does it take to decrease the usage of cpu??, cause I am sure people with slow connection and slow cumputers will have big problems with my site and propably will hate it.
