Control size of Facebook auth dialog

I'm using Facebook C# SDK for my WP7 app. The authentication dialog that prompts the us开发者_Python百科er to grant permission to the app is displayed full screen on the app (about 480px I guess), but the allow/don't allow button are hidden at the bottom of the frame, which needs to scroll. There is a large part of the screen that is white though, so I think Facebook is serving a dialog for a larger screen.

How can I specify the size of the screen when authenticating over Facebook oauth ?

This is a bug with Facebook. I would suggest opening a bug with Facebook at https://developers.facebook.com/bugs.

The one thing you might do to work around the issue is to inject either javascript or css into the page using the browser control. Your javascript/css could fix this issues and resize the page. I have done that before on an old WPF app and it worked well.

Unfortunately, the Facebook support for Windows Phone is very poor and there are several major issues of this type.
