Tasklist Advanced doesn't properly install when prefixed tables are used.

In .install file there is:

  // let's make sure that there's an entry in {tasks_advanced} for each existing entry in {tasks}
  // need to make sure all parents are turned into projects
  db_query("INSERT INTO {tasks_advanced} (nid, taskcategory, tasktype)
            SELECT t.nid, 'unknown', IF(t.nid IN (SELECT parent FROM tasks), 'project', 'action')
            FROM {tasks} t
            LEFT JOIN {tasks_advanced} a ON t.nid = a.nid
            WHERE ISNULL(a.nid)");

there should be:

  // let's make sure that there's an entry in {tasks_advanced} for each existing entry in {tasks}
  // need to make sure all parents are turned into projects
  db_query("INSERT INTO {tasks_advanced} (nid, taskcategory, tasktype)
            SELECT t.nid, 'unknown', IF(t.nid IN (SELECT parent FROM {tasks}), 'project', 'action')
            FROM {tasks} t
            LEFT JOIN {tasks_advanced} a ON t.nid = a.nid
            WHERE ISNULL(a.nid)");
