Compositor not applying to animation frames

When I render out my animation in the uv image editor I have no option to look at the composited version of my frame. Instead I have to go into a headin titles viewer node. The actual frames that are saved out are saved out to the un-composited version. Is there something I am missing?

A switch in the project properties pane to turn on the Compositor or make sure that the last node is connected to the Output Node. Otherwise it is hard to help you with no screenies or much detail as to the problem. Sorry

I figured it out, it turns out that when i duplicate the scene, when I delete the composite node and re add it everything works again.

Really?! Could be a bug, test it and submit to the bug tracker.
