Hi there,

I am trying to launch a Multibox (or similar) overlay from Flash, however as I cannot pass the class within getURL this will not work. I have heard that this can be done with ExternalInterface in as2 / 3 but haven’t found much clear documentation about it.

Has anybody else had any luck?

Many thanks in advance,  
Ben
