Actionscript transition really slow!

Hello

Trying out using a really nice transition that I found on flashkit. Here - [COLOR=#22229c]http://www.flashkit.com/movies/Effec…5431/index.php[/COLOR]

Tried tweaking the actionscript to my needs, changing the size of the squares in the script, and then amount of squares in order to cover the length of the images I want. Managed to get it, but now it runs painfully slow! I even tried taking the tweens out as I figured that maybe flash was trying to do too many things at once. But it still runs as slow without the tweens, which doesn’t seem to make much sense to me…am I missing something?!!

Any help much appreciated :wink:

Can’t attach my fla though…it’s 2MB. But the swf it publishes is 70k which shouldn’t be the reason for the problem I don’t think!

Thanks

Pat
