uMail Address line - auto fill

Can someone just tell me if the uMail address line in the TO and CC spaces are supposed to auto fill when you start typing the name? I think it did, but now it doesn't. Version 19.2

User types in "Jose" but there is no movement on the list ("Jose" does not pop into the space), user have to scroll down the list to find "Jose" highlighted. It works the same in Firefox and Chrome. Have not tested other browsers. I was under the impression that the name will pop up in the space you are typing in. Another issue: User position cursor in "To" space and start typing, Unifier only allows one letter, then the user have to actually re-position the cursor again to type in the next letters. It is supposed to work like this?
