Caller was on slide 18 of first module - Financial Management. She had filled in the answers previously and come back to the page and it wouldn't let her submit, but it also wouldn't let her move on. I tried to reproduce what she was doing on my machine and when I chose "Knowledge Check" from the Menu or hit the refresh button by the play bar, it would change the "Submit" button to the "Next" button. The caller said neither of those things happened on her machine. I was unable to help her further. The caller suggested we create menu items for slides 19 and 20 for people who might get stuck in the same situation.
