If someone wanders why the fullscreen doesn’t work correctly under IE, after calling StageDisplayState.FULL_SCREEN in Flex – there’s the answer. Just don’t forget to add
<param name=”allowFullScreen” value=”true”>
parameter of the object tag. You may also set allowFullScreen=”true” of embed tag.
Finally I found the solution. I had no idea the problem can be in HTML and not if Flex, but as it appears it can 🙂
Thank you!
