I have just noticed that the moodle wiki in our installation doesn't work well when setup in 'separate groups' and allows students assigned in Group A to check what students in other groups are doing - the students see the drop-down menu on the top right corner of the page that allows them to access other group wikis.
I am fairly sure that the groups have been setup correctly and each student has been assigned to one group only. The wiki option has also been turned to 'separate groups', but still other groups' wikis are visible.
Is this a known bug? Has anyone faced the same problem?
I would appreciate any help on that
P.S. Moodle version used 1.8.
