The text of comments entered in a student's submitted code file do not appear to be saved. If I, as a grader, navigate away from the code view page and return, the comment markers are still there (I tried suggestions and errors), but the text associated with them does not appear. Similarly, when I view the code as a student, I see the markers, but not the text.
I am using Safari 5.1 on OS-X 10.6.8 (in case that's a factor) with Web-CAT v1.5.0/18.104.22.16810609. We have auto updates enabled, and all subsystems appear to be up-to-date.
