Yes, this is the problem, but for now I go to wait the official patch. I dont understand the problem very well to apply the patch.
But, I make a new install of moodle to make more test. In the new moodle install, the problem of the Course creator being showed in all courses exist, but is different of my real moodle.
In my new installation, I create 2 users and put all in Course Creator's role.
I create a new course using the user1.
In this course participant list, the user2 is showed, but when I click in this user, it is not enrolled in the user1's course, it is only showed in "All Role" or in "Course Creator Role".
In my real moodle upgraded from 1.6.x, all course creator and site admin is showed in all courses and all course creator and admin is enrolled in all course.
I try to cancel the enrolment of all non participant people but it dont work.
