I've been looking for an alternative Testimonial widget, I came across yours and love everything about it; clean, simple and open.
I have three Testimonial widgets in my sidebar, each assigned to their own rotator (and each testimonial in this rotator is assigned correctly) but only the first widget will rotate.
I tried swapped them around and still only the first widget in the stack will rotate its testimonials.
The other two just display as list (I have checked the settings for that too).
I really want to use your widget, it is the cleanest available.
UPDATE: This doesn't happen if I use the shortcode in a template file.
