(PIII) Since joining a Windows 2003 domain, Thunderbird displays dialog asking if it should be the default mail client every time it is launched. Continues even if you answer "Yes". Windows "Set program access and defaults" utility lists Thunderbird as the default client. Tried to delete and recreate profile and completely remove Thunderbird and readd it, no avail. Which Registry keys should I be searching for as my next line of attack? No weird policies in effect, I control the domain. User has Administritive rights on Domain and local machine. Reproducible: Couldn't Reproduce Steps to Reproduce: 1. Only happens on this machine, can't reproduce elsewhere
1.5.0.x is no longer supported. Chris, does this still occur with the latest Thunderbird 2.0.0.x or trunk nightlies?
Nope, haven't seen it since the 1.5 days.
