Captivate 6 Quiz - "Click Anywhere to Continue"

I have a Captivate quiz that is 800X600 and have published it with Scalable HTML Content selected.

If I have the window maximized greater than the original 800X600, only parts of the screen will allow me to advance when I want to continue.  Each quiz slide in the project has a different area that you can click. Each time I visit the same quiz slide on another attempt, the area I can click to advance is different than the last time I attempted that question.

It's almost like the 800X600 clickable area is randomly spread around the newer, larger sized window.
