I'm putting together a popup flash player that can be launched from a url posted on a board. The link goes to a landing page which executes an onLoad script that opens the popup, then closes itself, leaving the popup over the board. Works fine in IE, but in FF the landing page remains open behind the popup and over the board. It will not self.close, and can't be closed from the popup (close.opener). Leading theory is that a FF window cannot be closed with script if it was not opened with script, and I've somewhat confirmed this, but seems a simple thing and should be doable.
