I looked at the code a few months ago with a friend in Iceland. If I
remember correctly... If it fails to use the proxy it will silently stop
using the proxy without any UI changes. Thus, you think you're using Tor
but the Bitcoin software itself doesn't tell you that it actually just
I admit, I didn't spend too much time looking at that specific issue but
it seems worthwhile to look into that as a possible issue. A full audit
of Bitcoin for use with Tor seems like a reasonably good idea, I'm
certain that Gavin would appreciate it. I've cc'ed him, so perhaps if
I'm correct, he'll hear about this directly.
