Hi there, I am running Moodle 1.3.3 but have had this problem with version 1.1 even.
When multiple users are logged in at the same time, and say one person posts a discussion message or a journal entry, sometimes Moodle displays (and records it in the db) as having been posted by the other logged in person.
I've seen postings of people with courses of over 200 people and I only have 45 total users!
Any ideas of why Moodle is not able to keep the users straight?
Thanks much!
