Windows can't run Vidalia Bundle and Tor Browser Bundle at the same time
A user is trying to set up a bridge with the Vidalia Bundle and use the Tor Browser Bundle for browsing etc. Setting up the Vidalia Bundle is not a problem and the bridge is up and running. When starting the Tor Browser Bundle, the browser never appears, and instead errors appear related to Tor not connecting to Vidalia due to path confusion. The Tor Browser Bundle works fine if the Vidalia Bundle is not already running.
I don't have OS X, so I can't really test this issue. See ticket 851 in RT for the full history and contact information for the user.
