Just curious, do your Project Owners, for examples the PMs running the projects, tend to mark tasks they know are complete at 100% on behalf of the users they are assigned to? In our case, less than 10% of our Task Assignees bother to go into their tasks and click "I'm Done". As a result, the PMs (including myself) tend to mark tasks at 100% from the Tasks view in order to keep the project schedule up-to-date. We have observed multiple cases where, since the assignee didn't mark the task "I'm Done", that they linger on timesheets for an extended period. And of course, once the project is Closed they have limited ability to edit/properly mark those tasks. How long do they stay on? At least a month but I don't have any hard data to back that up. They eventually do go away but it takes much longer than you would expect. Jason Maust McGuireWoods LLP
