I installed the moodle 1.8 and found some problems with the groupings within a course.

First, I create a grouping in a course. Then I create a group in a grouping. The moodle then create a new grouping with the name "[Not in a grouping](0)", and it place the created group in that grouping. When I delete the group, the grouping created by moodle is also deleted.

And there is some display problem with the grouping if I use IE 6 to browse the grouping page. In the "create grouping" page, "create group" page, "delete grouping" page, and "delete selected group" page, the textboes and buttons are mis-alligned.

The display issue is only for IE 6. It's not a problem with IE 7 and Firefox 2.
