Our SumTotal (Docent) 6.5 learning management system uses SCORM to launch learning activities and quizzes. We had a case where several Perception Quizzes would not launch using Safari, but any other browser did launch them.

On carefully examining the launch URL’s we found that for some reason they had been HTML encoded in the database. In other words, the & symbol was translated to &. When it was converted back to a “&”, the quizzes launched fine in Safari.
