Hi, I meet the same problem :(
my platform: 
Windows 7 Ultimate
Chrome 15.0.865.0 dev-m
Proxy Switchy!  1.6.3

I create proxy profile which manual configured as SOCKS Host 127.0.0.1:7070 and 
use SOCKS v5,BUT the Bitvise Tunnelier log shows it use the SOCKS v4.
PS: It's OK until I reinstalled my OS two days ago, and the Tunnelier always 
works well with FireFox6.0+AutoProxy.
