I've just updated 2007 Office beta 2 with the Technical Refresh. The Outlook offline cache hasn't survived and Outlook is trapped in a loop. Black mark. But Word had crashed just before I updated and I was having trouble getting into the auto-recovery files. I knew I could recover everything from ClipMate because I'd been copying between documents, so I decided to give up and install the refresh. After a rather long time with a very uninformative progress bar the refresh completed, warned me in a rather cryptic dialog that other applications would need updating too and showed the new and tasteful (or is it bland? OneNote is much less visible in the notification area) icons. I started Word - and there were the auto-recovered document in a task pane. Full marks!
And I do like the way the 'pinned' documents on the Recent Documents pane of the Office menu now have the pushpin both coloured green - and pushed in to the menu ;-)
