loading external SWF or IMG, why is width and height 0?

[jng]

I am making a slideshow and have an custom class "slide", which extends Sprite. The slides are loaded and then fade in and out.

In my main FLA file I load an XML file with slides, that contain either text, an image or an SWF clip. When I load an image or a SWF, my slide always have widths and heights of 0. I don't understand that.

It's a larger problem for the SWF (which doesn't center, although the images mysteriously center).

Additionally, the SWF starts playing immediately and I cannot figure out how to stop it and call it only when I want it and to keep it from looping!

Can someone please help me? Thanks.

try Event.INIT instead

Nope, it still doesn't work....
