I just started using Mail in El Capitan, and I have a major problem. When I'm composing a message, the from popup menu doesn't show. I've looked at the header options in the toolbar, and the from field isn't listed there either. Since I use aliases, this isn't good. I'm wondering if the from popup menu has disappeared? Or does VoiceOver no longer read the from popup menu? I have no vision, so I can't tell. I acknowledge that something strange could be happening on my system. So, any information about your ability to access the from popup menu would be helpful.
Thanks in advance for your assistance.
