There's gotta be a simpler way

Okay. So my little tabbed-based app is working fine. All is good. However, as I’m learning AS3 here, I look back in retrospect on the code and execution of this sample (see link below for sample file).

Thinking about this, I realize there has to be a simpler way to achieve what I have done here–I just don’t know what that is. I imagine it’s probably all possible with everything on 1 frame and all code in one spot in my movie. :smirk:

Can any of you veterans out there help me understand how this could be further optimized? Thanks very much for your insight and help on this.
