App Request Dialog has sides cut off when app is displayed in a Facebook page tab - how to make fit?

Seems that the area is only about 470 px wide for some reason? Not even 520. Maybe I can shrink the App request dialog somehow, but not seeing a param to constrain it. 开发者_如何学PythonIt seems to want to be about 570 pixels wide. Plenty of room if they just go straight to the App of course. Right now I'm doing it as a popup as a work around.

The facebook app "window" is 520px by 800px. Make sure you set padding and margin to 0 on your body element to take advantage of the full size.

I would try repositioning your app request dialog to make it fit within the allowed size.
