Release 31.3.0 was installed on 12/21/14. Since then the following occurs and is consistently reproducible. 1. Begin creating a new email 2. Begin adding a name. When autocomplete brings up a list, select other than the first name on the list. 3. Depress enter to go down for the next entry 4. The first entry is changed from what was selected, to the first name on the previous list. It makes it kind of difficult to enter emails in this manner. I found that selecting from the Contacts Sidebar is a workaround but kind of funky.
