Hello Chris Adams,
I'm sorry to hear you are having difficulties with the latest beta. Very few changes were made to the Project Dashboard, so I am slightly puzzled to hear about your problems. In fact, I have been unable to reproduce the little "circle of death" after installing Beta 4, so I'm thinking it's something more specific.
Could you send me the contents of the DashboardConfig.xml file? I'm wondering if something is corrupt within the file.. You'll find it in your Documents folder under Work Item Manager 2010\<your tfs server>\<your collection name>\<your project name>.
With regards to the iteration effort, this is what the iteration effort section for our project dashboard looks like:
<IterationEffort Enabled="true" UseGlobalPollInterval="false"
PollInterval="300" WorkItemType="Task" CompletedState="Done"
ExcludedStates="" CalculationMethod="Effort" TotalEffortField="Remaining Work"
RemainingEffortField="Completed Work" CompletedEffortColor="FF14BE00"
IncompleteEffortColor="FFFD6900" />
Can you check yours to see if the settings make sense? A word of caution, editing this file manually doesn't update TFS if you are sharing project settings.
Thanks,
Greg
