hey guys  
i m trying to open a fullScreen Flash window with ExternalInterface.addCallback function, basically a button in the html page calls the flash function which opens fullScreen window. Everything in the flash function (like fade in fade outs) work except the full Screen mode, if i put a button in swf it opens the full screen window on Mouse Down event  
when i try to dispatch the same event in the flash function it doesnt work either i think the problem is related to security settings  
already tried allowDomain but it didnt help either  
Security.allowDomain("\*")  
i m pulling my hair please helpppppp
