Our buddy Ken got his blog running: http://www.breakingwindows.com/.
Ken is a big Mac user who just setup a beast of an XP machine. He and I have been chatting, and he's really bringing to light some severely retarded Microsoft engineering.
Case in point: in order for the auto-complete to work in OutlookXP email To: field...you must first type the whole email in. Then it will work next time.
Basically it works JUST like the URL and form field auto-completes...which doesn't make any sense if you already setup all your contacts in Outlook, with nicknames.
