Alex,
The custom facebook image is the solution and it doesn't hang anymore when you are on the site. However when you send a request and the user gets the request, Inside the canvas it would just say loading and then just close without connecting. It doesn't connect the user.
I tried the autoconnect functionality that used to be working for 1.5 and enabled this
www.sourcecoast.com/forums/jfbconnect/jf...canvas-system-plugin for the JFBConnect 5.0 System Plugin.
This would cause the window to reload various times trying to connect. IE disappear and reappear until it gives a connection error. and this is both for Firefox and IE10.
I am undoing the custom change in the system plugin until we can at least find out why it hangs inside the canvas. The custom image is turned on in the ScLogin module.
