I've pieced this together from a tutorial on captions. My
goal is for a caption to pop up in a customized balloon when the
user rolls over a button. I'd also like the balloon to feel like
it's stuck to the end of the mouse while in the button's hitspace.
I think the way to do the above is through a startDrag and
alpha property script.
I'm having trouble getting the correct captions to turn off
and on (alpha) over the right buttons.
Plus, I'd like to gather all the script into the first layer
and just reference my movieClips and buttons.
