quiz "on last attempt" & "on success" actions w/ advanced answer feedback?

I'm using Cp 9 and the quiz I'm working on needs to have custom feedback based on the selected answer, and show/hide custom playbar buttons on completion to allow learners to move through the lesson and quiz. Unfortunately, in tests is appears that "on last attempt" and "on success" actions do not execute when advanced answer options are enabled on a question. With what I know at the moment, I could get around this by writing in some advanced actions/variables to separately evaluate question completion, and predicate my playbar behavior actions on those. It seems a bit silly to me to have to do that though, being that completion is already being evaluated... so, 3 part question:

1) Is the issue I'm describing an issue for you as well, or is it a bug in my work environment only that I can resolve with further bug chasing?

2) Is there a solution to this using the standard Captivate tools and options?

3) How can I access the completion variables for a particular quiz interaction? I'm comfortable writing some JS functions around them, but I'm having a hard time finding them in the first place.

Any help is much appreciated.. working under the gun a bit here.. thanks in advance!
