1 Instance works, 2 doesn't

Hey guys/gals,
I posted a while back about tweening vertices and prg9 had some great links. I used the Fuse example he posted and started to convert it into a class. Here is what I came up with, which works great. However, as you can see in Main.as, it only works one instance at a time, and the last instance that gets called to tween in the onRelease is the one that works. I can’t figure out why I can’t make more than one instance at a time, so if anyone can help out a bit, that’d be great.

I’m only attaching the two classes that make this run as it depends on some other classes that i have linked up as libraries in eclipse and I don’t want to put together a whole package of it, but if its absolutely necessary then let me know and i’ll repost a package of files.

Thanks.
