I can't move tasks within a task list what did I do wrong?

Tasks can be moved within general task lists only. That are the ones having a black label in the task list view. It is not possible to move tasks in search lists and in predifined lists like 'Tasks Today', 'Tasks this Week' and so. Furthermore, tasks can only be moved in general lists if the list is not in the recycle bin view, no filter is defined and if the task list is not sorted. Sorted lists are indicated by a little black triangle next to the column label. To remove the sort order you can click on the column label multiple times until the black triangle disappears.
