Facebook Login Window hangs after logging in -

when user logs in window hangs , it's title changes to: xd proxy

there similar question supposedly solved instead of posting solution user said: "i solved it. settings in facebook's page." ended knowing have change settings page no idea what.

my url in settings page is: http://chusmix.com/ , domain chusmix.com. i'm trying login button @ http://www.chusmix.com/game

i don't need refresh since login button refreshes logged in itself, need window close.

this code:

  <div id="fb-root"></div>   <script src="http://connect.facebook.net/en_us/all.js"></script>   <script>      fb.init({          appid:'146324722088262', cookie:true,          status:true, xfbml:true       });   </script>   <fb:login-button length="long" onlogin="signface_login();" autologoutlink="true"></fb:login-button> 

any info on how fix tremendously welcomed. have been trying fix last 2 hours , haven't been able start else.

thanks

btw 1 of solution can think of set next url in fb login page page call window.close() let me know if working fine....
