I'm not sure about the details of the current view setup - are we even involved on OS X when Flash goes fullscreen?

I don't know the exact details, but I'm quite sure our involvement is minimal.  So this is likely to be a Flash bug.  (Even if Flash works differently in other browsers -- all the major plugins sniff which browser they're running in, and often behave differently accordingly.  Sometimes all they look at is the user-agent string, and changing that is enough to change their behavior -- but that's getting more and more unusual.)

So the thing to do here is test Flash's behavior in other browsers, and test with different versions of Flash (http://helpx.adobe.com/flash-player/kb/archived-flash-player-versions.html).

Also test on different versions of OS X.

Benoit, which version did you test on?

Actually I wrote the code that interposes fullscreen. I think I'm just picking the primary display instead of the correct display:
