Circular Function not working

When I click on “Circular Slider ?” in the Slider Settings and Save Changes, the checkbox becomes unselected so I can’t get the slider to continue when it reaches the last picture. The “Pause On Mouse Over ?” selection isn’t working for me either.

I tried to making the checkbox checked by default in the code but this didn’t make the slider continue either, and that is about the height of my plugin hacking abilities! 🙂
