The Task Link dialog box opens upon clicking on a link directly in the Gantt chart pane.
This dialog box allows the user to edit the links to the following attributes: Logic, Lead/Lag, and Calendar.
Clicking on the grey Remove () icon empties the Calendar field. If no specific calendar is selected in the Calendar field, then the Project Calendar will be the one used by all tasks.
Users also have the opportunity to directly delete links from this dialog box by clicking on the Delete button.
