Hello all,

quick question. I have a lot of legacy projects that I occasionally need to update. These projects almost all use the Zigo tweens (lmc\_tween.as) which don’t appear to work in CS3 even when published as AS2. Is there a workaround for this in CS3?

What is the current preferred method for tweening with CS3 and AS3? I really like the simplicity of the Zigo system and if I need to replace it, something as simple and quick would be great. Is there an easy way to replace existing code with compliant AS3 code? Thanks!
