Editing teachers cannot import in Moodle 1.9.9

As noticed in several forum posts recently - here is one example http://moodle.org/mod/forum/discuss.php?d=155226#p679834
editing teachers seem to have lost the ability to import from other courses where they are editing teachers - it just tells them they are not editing teachers anywhere else. I have tried this on the demo site where the teacher is an editing teacher in all the courses and get the same message. I am not aware of any change in permission whereby teachers may not now import resources from other courses so would welcome comments or enlightenment
