Dear Martin,
Recently we upgraded moodle-1.3.2 to 1.3.3 and subsquently to 1.3.4.
In the later two versions, we found some discrepancies in the logs page.
When you click on Show these logs button, the logs are displayed, but some fields are found to be missing. (e.g. username, course name, topic name) in a couple of records.
And when you click on the hyperlink (Live logs from the past hour), it displays only one record.
I just copied the contents of those two pages into a MS Word file and attaching herewith. Please have a look at it.
Thanks and Regards.
Sujeet
