I try to open my swf in fullscreen mode by user clicking the button, without any success for now. I keep getting the "SecurityError: Error #2152: Full screen mode is not allowed."
My HTML looks OK with all possible allowFullScreen parameters set to true.

I suspect that my problem might be in the fact that I use lots of external swfs in my application. And to close the Error alert window I have to click several times on it.

How can I make my "fullscreen" button work?

I honestly searched Internet and Flashkit forums for the answer to my problem, but looks like nobody else was having it.
