As per Joseph Rézeau suggestion, I have posted this as a seperate issue.
I am testing Moodle 2.0 Preview 4+ (Build: 20100708) on a Linux/Appache server. I am using the Formal White Theme.
I have tables setup in the Lesson Questions with the width set to 100%. This causes the table to open wider than the question frame.
I reset the width to 800 px but the new setting is not saved. I also edited some text and the edit did not save either. However the edits I made were in the Moodle Auto Format editor... see: http://moodle.org/mod/forum/discuss.php?d=153713.
