In my ToDo list the Show ToDo for dropdown do not remembet my username. So when I check one of the checkboxes, Pinned Only og Empty Dates etc., it shows me the ToDO-list of the department and not my ToDo.

The Show todo For only shows up if you are an admin user, you might want to log in as a normal user, unless you need the admin privilege.

Okey

I'm having the same problem, is there any resolution for this? An administrator should be able to use this feature.

Okay I seemed to have fixed the problem by adding $user_id to the global list at the top of the todo_tasks_sub.php file.
