Basically yes.  Parents size their children in Flex and popups don't have a 
parent.  (actually they do because they are parented by SystemManager, but 
SystemManager doesn't layout its children.

Subject: Re: [flexcoders] Why does percentWidth / percentHeight not work with 
popups?


I can confirm the issue and had to manually size it via the resized event.

Maybe it's because the popup is not part of the window/app's display
list, but instead a separate controlled by PopupManager?
