The other day a Captivate author showed me a new problem: on one slide, resource links she had put into a slide imported from Powerpoint were not working.
At first I thought it might be a security issue or a problem with absolute vs. relative links, but it turned out to be caused by overlapping clickboxes. She had started the project by importing a Powerpoint file, selecting "Advance slide on click" rather than "Automatic advance" when importing. This setting creates large clickboxes that cover the entire slide, and the slide-encompassing clickbox was overlapping our link clickboxes.
We removed the slide-covering clickbox and added a Next button, which made more sense anyway, and the links now work.
One other thing to check, particularly if you are new to Captivate. When a clickbox is inserted, it has a duration. Check the Timeline to see that its duration lasts the whole slide duration, or at least until you will want to click it.
Flash Firebug is a great tool for debugging Actionscript 3 SWF files, similar to the way regular Firebug helps debug Javascript and CSS when using Firefox.
But the current version of Flash Firebug, 3.0.3, has a bug that causes it to display this error:
No SWF files with AS3 detected on this page. You could try reloading the page.
This can happen even when there definitely IS an Actionscript 3 swf on the current page. To resolve the problem, install any later version than 3.0.2, available from this site:
