Windows Mail in Vista.
My present laptop uses Vista, which also uses Windows Mail, a clone of Outlook Express, with which I am familiar and happy. ( not Outlook, which is a different animal )
'trouble is, even tho' I have ticked the option to automatically complete e-mail addresses when completing the address 'TO' line - it doesn't, and I always have to then go into my address book and select the recipient, not a major of course, but takes an extra milli-second - or two - which is irritating.
Occasionally it will oblige by showing the last address I used that starts with the same initial letter, but not always.
I might not even have known that this was possible, had I not had the pleasure of this assistance with Outlook Express on the old XP computer, and Gmail gives one the option of a few choices to select as you start to type.
Maybe it's the way I hold my mouth ? or perhaps it's called Progress ?
