AS2, Flash CS4. We’re using ExternalInterface to get callbacks from JavaScript for mouseover and mouseout when the user rolls on or off the .swf on a page. This works fine in all situations except for one:

If the .swf is viewed in Mac Firefox, and if there is a button or mc near the edge of the stage with an onRelease() event, when you mouse from outside of the .swf into the button, the mouseover fires correctly; but when you mouse out from the button and continue outside of the .swf, mouseout never fires.

We have built a small, simple testbed with only minimal code and assets (ExternalInterface code and a button). We are able to duplicate this consistently, on multiple machines. (again, Mac Firefox only).

You can view the testbed at:  
[http://clientdata.teracent.net/mouseout/noswfobject.html](http://clientdata.teracent.net/mouseout/noswfobject.html)

If you have Firebug enabled, you can also view debug output to the console.

Any suggestions appreciated. Thanks!
