If you have annoying scrollbars around your Facebook app's canvas, here's what you need to do:

First, go to your app's settings, click "Edit App" and then "Advanced" on the right.

Scroll all the way down to "Canvas Settings" and change "Canvas Height" to "Settable".

Second, add a call to FB.Canvas.setSize() (http://developers.facebook.com/docs/reference/javascript/FB.Canvas.setSize/). Make this call inside window.fbAsyncInit, after calling FB.init.

That's it! Gorgeous app, no scrollbars!
