---------------------------+-------------------------------
 New user, have been enjoying Tor for a couple days now. Windows 7.

 The Usual: connection window pops up, completes. After it disappears,
 browser window opens. Everything works well.
 The Sometimes: connection window pops up, completes. After it disappears,
 browser window does not open, and there's no response for at least 6 min.
 I just end the process after that.

 Turned on some logging. Closed the browser, reopened the browser, and
 repeated. It seems on the 6th try, got the Sometimes-hang. A difference
 from the other sessions was that no "New control connection opened" was
 logged at the end. Here are the last two sessions, one Usual and then the
 Sometimes.

 I don't expect this to be too useful, matter much, or be reproducible for
 others. I ran across it when I was trying to set Tor Browser to be the
 default browser with the options pane. I couldn't get that to work. Don't
 know why. However, if someone has seen this before or if something is
 obviously wrong, let me know what it is.
