frame animation

I brought in a frame animation, selected another element to engage the animation with a tap. But I forgot to rename the animation, so I changed the name. Then I went back to the frame animation to adjust the speed. When I selected the frame animation button I got this error:

An application error occurred while attempting to perform the last action.

Restarting InteractBuilder is recommended.
