Indexing Oddity

I've observed some odd behavior with the search indexer in Windows Vista, especially in the way it behaves with Outlook 2007.  Sometimes I'll find that certain messages are simply not showing up in a search, and when I open Outlook's indexing status I find it has gotten stuck, like so:

The number never updates.  This leads me to believe the way the search indexer interfaces with Outlook 2007 is still a little buggy.

There are some other odd behaviors.  On a whim, I tried to rebuild the index and disabled Outlook from being indexed, so I could see how long it would take to only index one set of items (the Start menu).  When I started the rebuild, it reincluded Outlook anyway.

I suspect this is an issue for Office 2007 SP1, but I'm going to post about this peculiar behavior over at the MSDN forums and see what turns up.  I know other people have had problems with the way the indexer "talks" to Office 2K7 and vice versa, so I ought not to be alone here.
