Problem with Live Preview when building components

I was wondering if someone has some links to good tutorials about building components for Flash MX. And then especially about Live Preview.
I’ve read some tuts like:

http://www.macromedia.com/devnet/mx/flash/articles/create_components.html
and
http://www.ultrashock.com/tutorials/flashmx/Components.php

but regarding creating Live Preview some things seem to be done differently in there. For instance, the tut on ultrashock places an instance of the actual component on stage in the live preview movie whereas macromedia’s tut does not.
Since I’m having problems with Live Preview when resizing my component, and also with the size of the bounding box I thought maybe one of you might know which is THE way to go?

Thanks in advance.

p.s. I feel like building components might also make a good subject for a tutorial here on Kirupa. Just an idea :slight_smile:
