Correct - you cannot add interactive objects to a question slide.
You could build your question using clickboxes for the multiple-choice
question, instead of using the standard quiz slide.
Alternatively, I think you can add a Button Widget to a quiz slide. You can
create your own button widgets in Flash.
Hi Steve, thanks so much for the quick reply!
The Button Widget does the job admirably, I can add it in and even make it invisible with the alpha setting so it appears that an image is the actual link. Totally lets me do what I wished!
Just to inform you that in CP6, we can add smart shape as a button to quiz slide, and set actions to it ( open url or file etc).
