First, let me confess that I know this is not a Fedora problem, but I think it's of interest to this list. We have a problem with some terminal workstations we're running. They boot Fedora (or Debian, some of them), and go straight into an rdesktop connection to a Windows Terminal Server. On the terminal server, we have a custom (but freely available*) kiosk version of Mozilla for the browser, and Thunderbird as a mail client. Something about Thunderbird is fairly funky with the Terminal Server. Thunderbird often does not terminate correctly, so people often get that message you get about choosing a new profile when they double-click to start TBird. It's confusing for them, and irritating for us. I know that this happens because of the presence of a lock file in the TBird profile folder. If we delete the lock file, then Tbird will begin to start normally. One potential solution is to write a new shortcut that 1) finds the lock file and deletes it first, then 2) starts Thunderbird. But this seems unclean. People might click it when Thunderbird is already actually running, and I don't know what that might do. We have no use for Thunderbird profiles, either in Linux or Windows. Everyone's already running within a unique user profile, and the Thunderbird profile only causes trouble. Is there any way to tell Thunderbird, Mozilla, and/or Firefox to just quit offering new profiles to each user? Or does anyone have any other suggestions for how to deal with this issue? Thanks, Matt * If you'd like to try our kiosk extension to Mozilla, find it at http://www.mozdevgroup.com/clients/bm/ . One day it should be an official extension, but that takes a while.
