I'm calling Adobe Captivate 8 lessons from an AS3 Flash wrapper, which we've been using successfully for many years for quiz-less Captivate lessons . Now, we're introducing quizzing and the radio buttons fail to appear.
Since I run the debug version of FlashPlayer, I have the added bonus of Flash Debug errors to share.
I checked around and saw that most of the time this symptom results from objects being inadvertently placed on top of the buttons (either in the Master Slide or actual Question Slide). However, I didn't find any conflicts there.
Here are the Flash Debug messages for a Question slide with 4 radio buttons.

As you can see, the Captivate lesson is referring to line numbers in ActionScript classes on my development system. I would think that Captivate would have embedded their own AS3 libraries into the published lesson SWF file.
So, I don't understand why it refers to my class libraries.
Regardless, the error seems to indicate that some sort of inability to draw the radio button.
Does anyone have any thoughts about what might be causing this?
