Full screen source rect, and onresize event question

So, I have my fullscreen working, selecting a rectangle to scale to. and everything is good there,… the issue is that the I have an onresize event, that positions the entire sprite… so… when it goes into fullscreen, it obviously fires the resize event, which inconveniently slides my content to the right, as it tries to recenter the content… any way I can make it so it doesn’t fire the resize event… i suppose not…

thanks for any help
