Ticket #1180 (closed enhancement: fixed)
Fullscreen exit from JS should be investigated
|Reported by:||zach||Owned by:||zach|
"The ActionScript that initiates full-screen mode can be called only in response to a mouse event or keyboard event. If it is called in other situations, Flash Player throws an exception."
My guess is that it's not possible to exit fullscreen from Flash either (even if the DOM object is removed), unless it's the result of a mouse / keyboard action, but this may not be true.
