Does the progress bar in top level work items show progress?

I have trying ot figure out how the progress bar works in a top level item.  I am using Out of the box Scrum process, RTC 4.0.3, RHEL 6, Windows RTC eclipse client.  The progress bar in the top level item never shows progress.

1.       Create a story with no children and save with owner, planned for, filed against, and priority  BUT no points and  save.  This is the progress bar:

1.       If I explicitly refresh story after save the progress bar changes to following.  The popup show Items with hours 100%.  There are no items with hours

1.       If I select point and save the pop up doesn’t change.  When I explicitly refresh the progress bar changes and the dialog

NowI create a task with no estimate and make it a child of the Story.  The progress bar changes to the following.  There are no items with hours.  I do not know what 75% means

1.       I now add an estimate to the task and save.  The story and pop up don’t change.  After refreshing the story I get the following. Not all items have hours – only the task does bit I guess at this point it also counting the story as having hours.  Is this correct behavior?

1.       I now add another task as a child with no estimate.  I get the following.  Only one item has hours but again I guess it is counting the story as having hours because of the rollup?

1.       I now add an estimate to the second task.  .  The story does not change – I have to explicitly refresh.  I get the following.  He sums are correct – only two items have hours

1.       Now I  record time spent against the first task.  I have to explicitly refresh the story.  I get the following.  I would think the progress bar would show something.  The numbers are summed correctly.

1.       I set the story into start working and tasks 1 and 2 into start working.  There is no change to the story.

2.       I now add more time spent to the first task. The sum of hours spent is correct but no change to the progress bar.

3.       I close task one – the progress bar is still empty

4.       I add time spent to Task 2.  The hours sum up in the story correctly

5.       Add more time spent to Task 2 and close it

6.       Sum in the Story is correct, progress bar is still empty.

7.       I close the story and the progress bar is still empty.
