BETA version -- 4.1.7.162

Yes, me too. Try portable x32 version, same thing also happens.

And then do you run the browser successfully or the same empty window without anything?

---

Avast blocks the .exe of the portable x64 version while downloading. Win32:Malware-gen. I stopped the antivirus and downloaded it.
AND NOW THE WEIRD THING: once I run the browser, it opens only a window frame empty inside, i.e. simply nothing. No tabs, no any contents, no anything. JUST AN EMPTY WINDOW! It opens successfully only in safe mode, don't know why.
Am I the only one who is experiencing such a situation with the new version?!?

Please, administrators and developers, give an idea how to solve this weird issue with the totally empty interface. It happens on Windows 7 Ultimate x64.
Probably something is wrong with the .exe packing or the files inside. The previous version still works fine without any similar problems.
