[SWFObject] Problem with SWFObject, ExternalInterface and Microsoft Windows Media Center

[Kareem Kouddous]

Thanks Geoff.

I removed the lines below from the swfobject.js and it fixed the  
problem. What do you suggest I do going forward? I wish I had the  
cycles to try and research and fix the problem but unfortunately I  
don't. I was thinking that a temporary band-aid is to leave these  
lines removed locally and manually merge any updates to swfobject  
until this problem is resolved. Do you see any issues with this? I  
only use swf on my page but I do steam FLV video.

deconcept.SWFObjectUtil.prepUnload = function() {
	__flash_unloadHandler = function(){};
	__flash_savedUnloadHandler = function(){};
	if (typeof window.onunload == 'function') {
		var oldUnload = window.onunload;
		window.onunload = function() {
			deconcept.SWFObjectUtil.cleanupSWFs();
			oldUnload();
		}
	} else {
		window.onunload = deconcept.SWFObjectUtil.cleanupSWFs;
	}
}
if (typeof window.onbeforeunload == 'function') {
	var oldBeforeUnload = window.onbeforeunload;
	window.onbeforeunload = function() {
		deconcept.SWFObjectUtil.prepUnload();
		oldBeforeUnload();
	}
} else {
	window.onbeforeunload = deconcept.SWFObjectUtil.prepUnload;
}
