Articulate Studio stuck on blank slide or question after selecting answer.

For anyone that runs across this thread later.  I submitted a ticket with 3 different examples of courses that became hung mid course.  They would become hung again after exit and relaunch since the problem is serialized and stored in the scorm progress_data value.

I only received generic email template responses from support with no resolution or escalation to a developer capable of identifying what the course did to it's internal state that causes it to to get stuck.

We just decided to suggest our customers upgrade their courses from Studio to Storyline or another tool that does not have this problem.
