Happened when I selected few countries with strict nodes enabled in config. A reinstall solved the issue but still not possible to trace down to the root cause.

Something more. NoScrip's XSS going wild. Even getting DDG search filtering warnings. And it uses a really big pop up to show that Allow or Deny window. Could you please check that one too?

Attached the screenshot on Dropbox this time.
