Full Screen Video is blank

Hi,

In my flex application, I set:

_view.stage.displayState = StageDisplayState.FULL_SCREEN;

but when that happens, all I get is a full-black screen with a message that explains how I can press Esc to exit this mode…

Any ideas what would cause that to break in this way? When I run my application through Flex Builder, the fullscreen works absolutely fine.

I’m using Firefox 2.0.0.12 with the latest Flash player version (115)
