How do I stop frame loop from hesitating?

I have set a sprite to continuously loop an animation, but when it hits the last frame it hesitates before starting the animation again.

Have you accidentally duplicated the first or last frame? Otherwise, without seeing the .capx, it's hard to tell.

I figured it out. Each of the frames gets a frame speed, and I accidentally changed one to 8. Changing it back to 1 seemed to fix the animation loop.

Good find
