I am becomeing more and more frustrated with CS6, but before I go completely off my rocker I thought I would post and see if anyone has 1) encountered these issues, and 2) has resolutions.
Here we go:
I hope that someone has an answer, especially for the quiz issue. This is potentially a deal breaker with CS6.
First off, even though we are at version 6 of Captivate, it has never been part of the Creative Suite. So it's technically incorrect to call it "CS6". In fact, if that's all you said about it without providing other info that helps us identify that it's Captivate, we would likely tell you, sorry, but the CS forums are this way.
As for the ActiveX message. There are essentially two ways to "fix" it.
Likely, you think your end users will encounter the same message, no? But I need to point out that this only affects things when running the Captivate content from the local file system. The moment you copy the Captivate content to a web browser and your user views it that way, the issue resolves and they will never see the message. YOU see it because you are the captivate author and testing by playing from your local file system before deploying to the server.
Sorry, I'm not a "Quiz" person. So I'm not equipped to coherently answer or guide you with what to do on the Quiz issue.
I am unaware of any way to control the size of the TOC to make it smaller. However, you may configure an Overlay TOC by clicking the Settings... button in the lower left corner of the dialog. Using an overlay will keep the TOC hidden until desired. When desired, the little icon is clicked and the TOC slides into view. Perhaps that will help?

Cannot answer about the first question, hope someone from Adobe will answer that.
For the second question: this is due to the fact that the quiz scope is now dynamic, a feature that has been asked for since long. To enable the user to navigate out of the former quiz scope, that started with the first scored object and ended with the last or with the score slide, now the quiz scope will only end when the score slide has been viewed. That means that - like in previous versions - the attempt is considered as finished when the quiz scope is left. Your problem is due to the new quiz scope: by navigating using the TOC without reaching the score slide, you never leave the quiz scope, so you still will be in the quiz attempt. Will try to look for a possible solution, but is this new feature that allows you to navigate to whatever slide you want for remediation not a possible alternative?
The TOC has a minimum width of 250px since it appeared. Only the size of the slide references has now changed vertically so that they will be visible and can be manipulated in the HTML5 output on tablets and smaller screens. And I really want myself to have more customization options for the TOC.
