I am resizing the height of a div using ExternallInterface.call based on the height of some dynamic components in my flash movie. I am also loading multiple images using the loader class. The javascript seems to block the loading of the images.

-If I load the images before the ExternallInterface.call I have no problems. However, if I use ExternallInterface.call before loading the images, the images don’t appear.

ACTIONSCRIPT:  
var eiEnabled:Object = ExternalInterface.call(“changeDivHeight”, newDivHeight);

JAVASCRIPT IN HTML PAGE:  
function changeDivHeight(windowHeight) {  
document.getElementById(“flashContent”).style.height= windowHeight;  
}

is this expected behavior? could anyone think of a workaround?
