Hi Mark,
This one is actually a bug, in that I was able to replicate the issue here and fix it. The problem was that even though we defined the inner div as the slideshow container using the "comments" class, by default it was still using the outer div as the next button to continue immediately to the next slide when clicked so this was hijacking the click event of the link even though it was outside the slide show container.
So this will be fixed in the next release coming within a week or so and the fix will also be in the repository later today for those working with the source code.
With the fix, the onclick is not even needed in the link, it just needs to be outside of the slide container to work normally.
Best,
Joe
