Recalculation of allocated hours when assigning/unassigning users
By default, Easy Projects recalculates personal estimated hours/hours left of the assignees as new assignments are made. If you do not want this to happen, such as when you need to have the current work loading unchanged, clear the 'Recalculate hours shared among assignees' checkbox. As a result, no change will be made to the current allocation of working hours.

Only those activities that user’s permissions allow her to edit/delete are available for selection.
