Hi,

I am writing a flash script that needs to put on stage about 1,000-10,000
movie clips.
Unfortunately, this application is extremely slow, and practically crashes
Flash.

I am wondering whether this is an inevitable result when working with
thousands of movie clips.

Does anyone have an experience with working with thousands of movie clips? Any
recommendations??

for each movieclip instantiated, flash must track all its parameters. that's
cpu intensive when you have large numbers of movieclips instantiated at any one
time. you should use removeMovieClip() for movieclips that no longer need to
be tracked.
