Have upgraded to TBB 4.0 on a Windows 8.1 box. When I start Tor the log tells me:
16/10/2014 12:43:12.829 [NOTICE] Bootstrapped 85%: Finishing handshake with first hop. 16/10/2014 12:43:13.280 [NOTICE] Bootstrapped 90%: Establishing a Tor circuit. 16/10/2014 12:43:13.452 [NOTICE] Tor has successfully opened a circuit. Looks like client functionality is working. 16/10/2014 12:43:13.452 [NOTICE] Bootstrapped 100%: Done. 16/10/2014 12:43:14.506 [NOTICE] New control connection opened.
but the Tor window says
Something Went Wrong! Tor is not working in this browser.
What have I done wrong?
