[Orgmode] Trouble with Properties and Sparse Trees/Agenda View

[Tom Shannon]

In my never ending search for good organizational tools I've come back
to try org-mode again.  The concept of using tags wasn't that
appealing to me but the addition of properties and columns makes it
now very feasible.  I am, however, running into problems associated
with these new features.

I'm using org-mode 6.24b and emacs 22.2.1 under Ubuntu Linux.
Creation of sparse trees and agenda views based upon tag matching is
working very well for me.  Creation of sparse trees and agenda views
based upon properties fails spectacularly.  So badly in fact that I
know I must be doing something wrong.  Here's a sample org file:

---------

* Tasks
  :PROPERTIES:
  :Task-Status_ALL: "Not Started" "In Progress" Waiting
  :END:
** Shannon, Thomas R.
   :PROPERTIES:
   :Contact-Name: Shannon
   :Task-Status: Waiting
   :END:
*** TODO This is a task
*** TODO Task 4
**** TODO Task 2
**** TODO Task 3                                                       :Tag1:

* This is a heading
** TODO This is a task
** TODO Task 4
*** TODO Task 2
*** TODO Task 3

----------

Creation of a sparse tree (C-c / m) with a tag match "Tag1" give the following:

* Tasks...
** Shannon, Thomas R....
*** TODO Task 4...
**** TODO Task 3                                                       :Tag1:
* This is a heading...

So far so good.

Creation of a sparse tree (C-c / p) to match the property
"Contact-Name" with the value "Shannon" when prompted gives this:

* Tasks...
* This is a heading...

I expected:

* Tasks...
** Shannon, Thomas R....
* This is a heading...

Trying to create an agenda view based upon a property is even worse.
I can't get a search using C-c a m to match anything but tags.

This functionality is make-or-break for me.  Any indication of what
I'm doing wrong would be greatly appreciated.

Thanks,

Tom S.
