Create a simple hierarchy of game objects as follows:
Empty Game Object
-> Cube
-> Sphere

Create an animation on the empty game object (Anim1)
Record keyframes for the sphere
Create a second animation, using the drop down in the animation window (Anim2)
Select the cube
--> Animation window reverts back to Anim1, when it should stay on Anim2

If user does not notice, cube will be keyframed under the first animation, not the second.
