[Plugin: Portfolio Slideshow] Caption text only wraps on first "loop"

Love the plugin (using the free version for now) but hit a weird glitch. When I load the page the first time, the slideshow plays and the captions all display correctly, no problem. But if the slideshow gets to the end and loops, or if you click back to an image that’s already played, the caption doesn’t wrap, instead running off the edge of the page.
