I have been using Thunderbird for some time now. I downloaded the newest version yesterday, and I can not get it to start. I have downloaded and reloaded it a number of times and get the same result. It won't run. Any ideas. I did reload my OS X 10.5.8 system, but archived everything in the process. It was after that that Thunderbird wouldn't work. So downloaded the newer version.
Thanks, jholm
