Do you use CompuServe? Word is, you can't use Windows Vista if you want to use CompuServe software.

What I want to know is, *why* won't CompuServe work with Vista?
Does anybody have instructions on how to connect to CompuServe without using CompuServe software? I'd much prefer that a workaround be found, rather than users not install Vista if that is what they want to do - the security improvements are worth the effort.
