TorBrowser closes and reopens unexpectedly after selecting New Identity via Torbutton
Manual selection of New Identity via Torbutton often causes TorBrowser to close and reopen but it's infrequent. It doesn't appear to affect TorBrowser's core function as opposed to just displaying unexpected behavior by causing the Web browser window to close and reopen.
I initially considered it something which perhaps I just hadn't experience of before as I prefer to use Vidalia Control Panel to use its functions instead; which are neigh identical to Torbutton. But it is behavior which I neither expected nor could anticipate and so I often made a choice to stop using TorBrowser altogether because it didn't feel safe to continue to do so; instead I chose to extract another copy of it and begin to use TorBrowser anew instead.
Circuit creation is as I'd expect if I select New Identity via Vidalia Control Panel but unlike using Torbutton it doesn't cause the TorBrowser to change its behavior whatsoever.
