TMGR: Indented Tasks Change Unexpectedly After Set Dependency

Microsoft Team Manager may unexpectedly reschedule the order of indented tasks if task dependencies are created among the subordinate tasks.

Microsoft Team Manager assumes an implicit dependency when tasks are indented to create a summary. Team Manager schedules the tasks in a finish to start relationship in the order of entry. If you then add an explicit dependency, which is a higher priority dependency, by creating a link between 2 of the indented tasks, Team Manager may reschedule the tasks in an unexpected way. The tasks may no longer be ordered in the order of entry.

This behavior is by design.
