Question

Answer 1

I tried to use FB.Canvas.setSize(e); to resize my app, but it did not resize at all.

I took a look in the Facebook Javascript and found out, that FB.Canvas.setSize calls the FB.Arbiter.inform('setSize',e) function.

If I call the FB.Arbiter.inform('setSize',{ width: 760, height: 1480 }) function right from my code, the canvas resizes correctly.
