"Start Vidalia when my system starts" nonsensical with TBB
When using that option, the system will launch a Vidalia on next boot for me, but the entire TBB context is missing, meaning settings are wrong and no firefox gets launched. We should probably completely remove that option for TBB, unless we can make it work so that it actually starts TBB at system launch instead of just Vidalia. Some indication that this takes place, like "Start Tor Browser Bundle when my system starts" or so would also be a good idea, I bet.
