Resume function erratic behaviour
We have a course written and running in Studio 09; it has run (with updates) for 3++ years. earlier this year we got feedback that after a student logged out during the course, when it was resumed the boxes would appear for "do you want to resume where you left off", "Yes" and "No", but there is no text in them. The boxes function correctly, ie if the box where "Yes" should be is clicked, the student is taken to the slide from which the Exit was made.
We have checked that in the Player Template > Text Labels the text is entered against the buttons. We have also checked that in Player Controls the box for "Prompt to resume on presentation restart" is checked.
We have about 10 courses running in Studio 09 on the LMS, and 2 in S13, but this problem only occurs with this course.
All ideas welcomed!
