I finally got Eudora 7.1 up an running on my new quad core Win 7 machine using the Programs (compatibility) method you all were kind enough to share. When I answer the question about being the default email program in the affirmative, it says there is something wrong with the registry and it won't be set to be the default. If I go to the default program routine accessed through the start menu, it is not listed as an email possibility. How can I make it (Eudora 7.1.0.9) the default program in Win 7?
