I have downloaded that new Version 18.104.22.168.59, Updated June 29, 2015.
When open for first time the splash screen freeze on the last thing (Restoring screens).
And so I do open another time, and the program run complete and ask my about the user/password for the proxy.
I can´t do nothing with first run, just terminate it by task manager.
So I go to the Preferences options 2, Web Browser and Proxy, Proxy definitions and set proxy manually by using authentication user and password, and problem was "solved".
