No, seriously. I installed it, tried to run it, and my running copy of Thunderbird came to the fore. Closing Thunderbird and running Eudora brings up a seemingly broken copy of Thunderbird, rebranded as Eudora.
I was never much of a fan of Eudora back when it was actually a real email client, but I’ll try anything to replace the bag of fail that is Thunderbird v2. That said, Eudora is more of the same. Don’t bother. Additionally, it hosed my existing Thunderbird install. My in-app icons are all missing now.
