are you using animate pro 2015.2?
if so, attach a screenshot of what you see in the publish settings.
if not, update.
The responsive options have only just been added, it's not surprising if an old screenshot doesn't include them.
Do you know the Flash scaling mode you want to replicate?
(@ch, that ss shows scale option.)
Right, I had things the wrong way round. Either he's not in HTML5 Canvas, or he's not using 2015.2.
