When I go into my Address Book to Edit Name, the account page is greyed eg no action possible. In order to edit account name, I found it necessary to open a prior email and do the editing there by rt click on Name in email/Edit Contact . There are problems when trying to edit/delete email addresses ... so far I cannot find how to take this action. In Edit Contact as before, all you can do is to go to Edit Details which then redirects to the same Contact listing which is greyed out. When in Address Book to create a new Contact, this again is greyed out so no action can be taken. I have 115.3.1 installed ... the latest version
