Eudora tells me to click on Tools then Signature; then I will be able to click on 'new' and write a signature or select from a list of previous signatures. I can't contact Eudora by phone without reregistering and am loath to spend the $30 or $50 for reregistration for 1 phone call. I searched their online help but found no answer.
I have reinstalled 5.2 but that helped not at all.
What happens is that when I open Eudora, and click on Tools and then Signature the item list in Signature vanishes. That's it! In all other respects Eudora is working just fine.
I am running XP.
