Combobox breaks b/c of no stage access

So I've got a swf that's loaded from one domain into another, without the host swf setting Security.allowdomain.

The problem is I'm using comboboxes in the guest swf, which try to add a few listeners to the stage.

I'm able to work around one issue by setting a flag when a CB is opened, then having a catch-all mc listen for clicks, see if they're open, and close them and use focus manager to shift focus.

However, the scrollbars in the list boxes don't work. Any ideas how to work around using a combobox without stage access?

I'm guessing you don't have access to alter the guest swf?

There's the Event.ADDED_TO_STAGE event that is suited for this sort of thing...
