Avast Safe Zone - Web Browser not fonctionnal

Hi,
Since the new update (version 2015.10.0.2208), when we open “Web Browser” into Safe Zone, and when we enter a web address nothing happen.
Parameters and configuration show a blanck page.
when we try to enter a parameter as chrome://config or chrome://flags or chrome://plugins and so on, we also obtain a blanck page

thank you for a prompt answer

Best regards,

Help me please :c
