when using simple example like at
https://developers.facebook.com/docs/reference/dialogs/oauth/
after auth box prompting for additional permissions appears, it jumps around the screen, and there is this message in the java console
Unsafe JavaScript attempt to access frame with URL https://s-static.ak.fbcdn.net/connect… etc.
The unsafe message can be ignored. It just happens before the cross domain loader code has initialized.
Never seen the chrome issue. Could you provide version numbers of browser and OS please?
