Description

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.2; en-US; rv:1.8.1.14) Gecko/20080404 Firefox/2.0.0.14

I built a application, in which there will be two sections. one will show a flash animation and other will show the static html content. To make things clear we will call these section as "animation section" and "static section". At any time in my application only one of these sections are visible. And initially when my application loads the "animation section" will be visible.The navigation between these will happen through a button . I am embedding the two section in to html '<div/>' tags and controling the visibility of these div's with elements style property.

to show a section : elm.style.display="block"
to hide a section : elm.style.display="none"

The navigation between these sections works great on internet explorer 6 and 7. But in firefox first initially application show the "animation section" and hides the "static section". Now animation plays without any problem. Now i switched to "Static section" by clicking on a button. With this "animation section is hidden and the static section is now the current section. Now if i switch to the animation section, this time the animation doesn't play. 
With my observation what i found that : I think firefox is trying to reload(re-construct) the animation ,when the element containing it coming to focus). Some thing failing to play the animation...

The second thing i did was : instead of changing the element's display property i tried to change the "opaque" property. This also giving the same results. I demonstrated the same in my code.

----------------------
About flash Animation: 
----------------------
The flash animation file is built using Adobe's Flex, in which i load the contents of an xml file and parse the xml file and plays the animation.(to get the xml data i use the flex's HTTPService, the xml file is deployed with swf file).

----------------------
source code:
----------------------
1. main file(index.html)
-------------------------------------------------------------------------------

<head>
<script type="text/javascript">
var section=1;
function swapSections(){
	alert(section);
	if(section == 1){
		alert('hi');
		section=2;
		//document.getElementById('one').style.display='none';
		//document.getElementById('two').style.display='block';
		removeClass(document.getElementById('two'),"hide");
		addClass(document.getElementById('two'),"show");
		addClass(document.getElementById('one'),"hide");
		
	}else{
		alert('cool');
		section=1;
		//document.getElementById('one').style.display='block';
		//document.getElementById('two').style.display='none';
		removeClass(document.getElementById('one'),"hide");
		addClass(document.getElementById('one'),"show");

function hasClass(ele,cls) {
	return ele.className.match(new RegExp('(\\s|^)'+cls+'(\\s|$)'));
}
function addClass(ele,cls) {
	if (!this.hasClass(ele,cls)) ele.className += " "+cls;
}
function removeClass(ele,cls) {
