[osflash] Flex: transparent objects

[Alvise Nicoletti]

Hi guys... probably that's not the right mailing list, but I'm starting 
to try Flex and I'm really amazed...

The only  thing that actually I'm not able to do is to set items ad 
transparent, in this case a TABNAVIGATOR.
It's white and the background image is covered.

What can I do?

And... to don't fuss you anymore, wich manual and documentation do you 
use to understand the properties and so on?
