First image in gallery is stuck

Question

I'm working with an image gallery and the first image in the transition ends up stuck near the bottom of the file, but the remaining images fly right into place.
I have a sneaking suspicion it may have something to do with my positioning somewhere or with my tweening. I added a global variable thinking it may have something to do with garbage collection causing my tween to partially stop, but that didn't solve the problem. It's just that first image when it transitions onto the stage. After that, everything works perfectly. Even the click transition.
This is part of my final project and given that I get this fixed, everything will finally be working. Everything is built using as3, so you could just copy and paste it, if you'd like. Except, of course, for the url button which is imported from the library and the text format which can be faked with any embedded font and exported as Myriad.

Answer 1

Here I thought I was using OOP. Apparently, I need to do more research into OOP and practice more on the structure.  If you think that's hard to look through, you should see the project it goes with. It's awful in there.
You guys are happy and concluded this is a good code, so that's all good - but just FYI this is a procedural code and worth noting there is another way, namely OOP, which would have prevented your problem in the first place!  Yes I can imagine how "awful" the whole thing would be... Anyway definitely I'd recommend looking into OOP if you're into more complex stuff in the future. It will save you a lot of time and headaches.
(And do not use those parallel data arrays if you can - that's truly "awful" )
