I'm running into a problem with a set value error in the middle of my lesson - it only happens on Vista Business machine running IE 6 and IE 7. Error does not happen when I use FireFox with Vista Business. Lectora reports to the LMS, "SCO window closed prior to Finish, calling LMSFinish." Then a window pops up stating, "LMSSetValue Error: cmi.core.session_time to [] General Exception" When I click okay, the Lesson browser window closes and when I relaunch the lesson, it does not bookmark where it closed out. I ran the same lesson on multiple machines (other than Vista Business) including Vista personal and Windows XP with IE 6 & IE 7 and did not have this error. We are using the latest version of Lectora to develop - along with Inquisiq LMS. Any suggestions?
