Version 4.5 dont close new PopUp windows when login ends from LightBox

Hello
I have met with the unpleasant experience of upgrading to 4.5 and see how when I login In from a active LightBox ( pritty photo ) the new Login Radius popup window does not close when it finish registering and instead it load the current url in this small window. This not happen with version 4.0.1.
I trayed to reinstall 4.5 and nothing change.

I come back to my old 4.0.1 and works Ok but would like have the last version 4.5 improvements.

Any idea to solve this?

Thanks
