When selecting a project other than the one selected by default, the Task Board and Chart Board links disappear from the green menu bar. The reason for this seems to be that their style is set to 'display:none'.
The Task Board and the Chart Board are only available for the "Scheduled Versions" so if you switch from a project to another and you see the Unscheduled box highlighted you shouldn't see this items in the menu bars.
Basically the Unscheduled doesn't have a Task board nether a a Chart Board.
