I think I've figured out what's going on, but I'm not sure there's an easy fix.
The animation applies <span> tags around each word in the text block. Each time the user navigates back to the slide, another set of <span> tags is applied and they build up. Is there an easy way to clear that? (I don't use <span> tags in my code so a universal command might work, though I don't know if the slideshow script applies any.)
I'm also going to play around with forcing a page re-load to clear everything.
