Multiple Anomalous Quiz Behaviors

Sigh. Another day deep in the eccentricities of Cap 6 quizzes. I am dangeroulsly close to a rant. The only thing holding me back is the fact that somehow it's my misunderstanding that is blinding me to the obvious.

I have a few issues.

Here's what I want to do. Naturally quiz scope is part of the issue but there are other unrelated anomalies.

I want to have review questions worth zero points interspersed in the course. If user fails final test and clicks retake, an advanced action on the first review question jumps them to the first exam question if a user variable is set to true. I set that variable upon entering the first exam question.

Problem: the action on the first review question does not execute. The variable value is true but the jump to the exam does not happen. Any reason such an action would not execute?

Next problem: scoring anomaly. My quiz is set up for 90% accuracy pass. If I fail all the review questions and pass the exam questions, quiz is passed and all is well. Since review questions have no points assigned, they do not figure into the accuracy calculation. However, if exam is failed and retake button is clicked, the score is not reset. That is to say, all exam questions are passed second time through but the accuracy is not updated; old score is shown and the exam cannot be passed second time through. It's as if the retake button is failing to reset score. Quiz attempts is incremented but score is not reset. Just don't get it.

Next problem: For the review questions, the playbar remains visible. If the learner wants to skip the question, learner clicks Forward button in play bar. Now I had always thought that the forward button was "jump to next slide" and not "continue." Maybe I have that wrong. In any case, after Forward is clicked, the review question slide remains on the page and the playbar advances to the question timeline button pause. If learner then clicks Forward again, rather than advancing to the next slide, a phantom timeline plays! It plays for 20+ seconds, even though the question slide has two seconds indicated via the default question button on the timeline. To make matters worse, after the phantom timeline executes, the slide is locked! No navigation is possible, Playbar is disabled. What the heck...

Next problem: This is a nit but still frustrating. I cannot change the font of my score and quiz review text. I have changed the default review and score text styles in the style manager. The template style, review area ands score variable fields shows the same but the text displays in a diff font. I swear I've done this before. I know I can create custom quiz review messages but... what the heck. Is this a bug or am I missing a setting?

I know there are probably workarounds to code for sime of these behaviors but either I am missing something or the stock behaviors are buggy. And if the soluition is "Delete your preferences file" I am gonna lose it.
