Greetings,
My images and captions occasionally become detatched from each other as in here (see bottom of page)

The only think I can associate with this is when I try one configuration of the image settings and then change my mind. If I go back and make the changes there is nothing in the world that will make the image and the caption appear together again. I have deleted all image related html in the post and also deleted the image itself. No go. Then if I move on to another page there are no problems. BTW, I am using the WP captions classes.
