How do I edit old animations in Unity 4.3?

We were running Unity 4.2 and had created a bunch of animations with the animation window. We just upgraded to Unity 4.3 and now when we click on the object the animations are attached to the animation window doesn’t get populated. I can’t find any way to view or edit the animations. I know stuff with the animations changed what am I missing?

We needed to set the inspector to debug mode and set the animations to type from 1 to 2 which made it so that we could edit the animations.

Changing the debug mode didn’t help me with one particular legacy animation, but putting the animation on a new throw-away game object for some reason made it appear for editing. I did my edits, deleted the game object, and the animation edits carried over to the animated game object that I care about.
